Abstract:                                ! Free format text

We propose 398   parallel orbits to constrain the Hydrogen reionization edge in
emission that marks the transition from a neutral to a fully ionized IGM at a
predicted redshifts \zion~eq5--10. The edge is due to a rapid change in
recombination from the Hydrogen Lyman series at z~eq\zion Baltz Etal 1998),
which leaves a sharp signal in the recombination spectrum \cge 3 dex below the
Zodiacal background. \zion is one of the most important remaining unknown
quantities in cosmology. HST is unique in that it can constrain this signal
with the STIS CCD plus long-slit, covering Lambda~eq5240--10,270Angstrom\ or
z~eq3.3--7.5. In Cycle 8, we took 28 STIS parallel orbits with contemporaneous
calibrations to reduce systematics, and set limits to the Hydrogen edge signal
of   2* 10^-21 erg/cm^2/s/Hz/sr at \zion\cge 5.  This 28 orbit data set has not
yet pushed STIS to its absolute calibration limits.  We therefore  propose
parallels in ~260 high and sim100  lower latitude fields (1--3 orbits each) to
map any variation in the Zodiacal spectrum across the sky. The combined data
will allow us to improve constraints to the Hydrogen reionization edge at 5
\zion  7.5 by a factor of 4, within reach of theoretical predictions. We must
develop this technique to learn how to optimally develop instruments for NGST
to make this measurement with greater sensitivity and at higher redshifts
(z~eq7.5--15).

     Observing_Description:

(1) STIS Parallels at high and lower Ecliptic and Galactic latitudes:\ In Cycle
8, we obtained 20 parallel fields at high Ecliptic and Galactic latitude
(\vert\bEcl\vert, \vert\bII\vert\cge 30^o), in regions of known low \NH or low
\EBminV (\AB  0.10 mag), \cge 4' away from any known SAO stars, and \cge
6.0*\re away from RC3 galaxies. This guarantees the cleanest possible
background for the Hydrogen reionization edge project. In Cycle 10, we request
further STIS parallels at both high and   lower Ecliptic and Galactic
latitudes, the latter in order to produce a better average,
moderate-resolution Zodiacal spectrum all across the sky. The Table on page 2
summarizes the request. The significant number will allow us to median out
discrete stars or galaxies which may fall on the STIS slit, and to get a good
measurement of the Zodi+DGL component. mn  (2) S/N and Time requirements for
the parallels:\ The high latitude fields have SB(V)~eq22.5--23.3 \magarc, and
the low latitude fields SB(V)~eq22.1--22.5\magarc. The ETC then predicts for
each 2- orbit parallel a S/N~41 per pixel at Lambda~7500Angstrom\ after
collapsing the ~1000 spectral pixels. The combined data set will have a S/N~600
per collapsed spectral pixel if global systematics (flat field and other
vertical gradients) can be removed to within 0.2\ able to do due to a lack of
exposures and fields.  But in principle, we can set limits on the Hydrogen
reionization edge feature at levels of 1.6* 10^- 4 of the zodiacal flux, or
1.5--5* 10^-22 erg/cm^2/s/Hz/sr, as indicated by the predictions for this
experiment in Fig. 3, which are ~0.6 dex below the upper limits from the current
Cycle 8 data.



TO FIRST ORDER, THE TARGETS ARE SELECTED, THE DATA ARE TAKEN AND THE ORBITS ARE 
FILLED AS FOLLOWING:


A) SELECTION OF PARALLEL FIELDS:

During the first part of the Cycle, we preselect targets to get a maximum
range in Galactic latitude, using the following two different generic targets:

1) HIGH-GALACTIC-LATITUDE, defined as ABS_BII > 30D
2) LOW-GALACTIC-LATITUDE, defined as LII = 180D +/- 135D, BII = 0D +/- 30D
   (i.e. the low Galactic latitude belt except for 90 deg around the GC).

If this does not yield enough variation in Zodiacal foreground (which we also
need for our purposes), then in the second half of the Cycle, we will change
the target selection to get a maximum range in Zodiacal latitude, using the
following two different generic targets:

3) HIGH-ECLIPTIC-LATITUDE, defined as ABS_BETA > 30D 
4) LOW-ECLIPTIC-LATITUDE, defined as LAMBDA = 180D +/- 60D, BETA = 0D +/- 30D
   (i.e. the low latitude Zodiacal belt except for 240 deg around the Sun, ie.
   only selecting a 120D range around the anti-Sun for maximum darkness, and
   so staying away from the Earth's limb).


B) TAKING OF THE PARALLEL FIELDS WITH STIS/CCD/G750L/52x2 or 52x0.5" slits: 

Taking the Cycle 9 primary exposure time distribution as guideline, our 398
Cycle parallels will be roughly split as following:

High Latitude (|b_II|>30)        Low Gal Latitude (10<|b_II|<30) 
240 1-orbit fields = 240 orbits    94 1-orbit fields =  94 orbits 
 14 2-orbit fields =  28 orbits     6 2-orbit fields =  12 orbits 
  6 3-orbit fields =  18 orbits     2 3-orbit fields =   6 orbits
------------------------------------------------------------------
260 Hi-Lat fields   (286 orbits) + 102 Low-Lat fields (112 orbits) 
362 fields in total (398 orbits in total)

Part of the low-latitude fields will be deliberately pushed close to the Earth's
limb (by using 2400 sec science spectra) with the 0.5" slit in order to get a
better measure of a bland of O-I lines around 8457 Ang (and O-I lines at 7320
and 6300 Ang) that may be generated at high-altitudes (Windhorst et al. 2000),
and that can be confused with the H-edge signal. 

This project will be three kinds of parallel fields, as following:

1) We need about 30 fields at LOW-GALACTIC-LATITUDE in the 0.5" slit to see 
   any DGL emission lines that may contaminate our H-edge signal. These also are
   pushed close to the Earth's limb in order to see the bland of O-I (?) lines
   at 8547 Ang at higher resultion, and any other lines that may contaminate our
   signal. We cover 1--5 orbit cases, which are in visit 1--5. We give this
   part highest priority, and will turn it off as soon as we have enough
   LOW-GALACTIC-LATITUDE fields with the 0.5" slit.

2) We need about 360 fields at LOW-GALACTIC-LATITUDE in the 2.0" slit to
   constrain the H-edge signal at maximum S/N across the sky. These will
   NOT be pushed close to the Earth's limb, but forced into DARKTIME. 
   We cover 1--5 orbit cases, which are in visit 6--10. We give this part
   the middle priority, and will change its priority if needed. These
   will be mostly 1-orbit cases, although we will follow and accept the natural
   orbital distribution of prmaries in Cycle 10. 

3) We need about 70 fields at LOW-GALACTIC-LATITUDE in the 2.0" slit to see 
   any DGL emission lines that may contaminate our H-edge signal. These will
   NOT be pushed close to the Earth's limb, but forced into DARKTIME as in 2).  
   We cover 1--5 orbit cases, which are in visit 11--15. We give this part
   the lowest priority, and will bump it up in priority if halfway through the
   Cycle if we don't get enough of them. 


C) PARALLEL ORBIT FILLING: 

Cycle 10 project 9066 has been allocated 398 parallels at high and low Ecliptic
and Galactic latitudes. Through our 36 orbit Cycle 8 pilot program 8260, we
learned how to optimally schedule these STIS parallels and their required
on-orbit calibrations with RPS2. Analysis of the Cycle 8 spectra and
experimenting with RPS2 shows that our typical Cycle 10 parallel orbit should
consist of the following calibrations and science exposures:

The exposures are numbered as VON, where V=the above visit number for each
latitude case (V=1--5), O=the orbit number in each visit (O=1--5 AND O=<V),
and N=the exposure number in each orbit, which are numbered as following:

N:

1-2) Two 60-180 sec direct finder exposures with STIS/CCD/50CCD to find any
   interloping objects to R=27 mag. These 
3) One STIS/CCD Wavecal for wavelength calibration. Together with the primary
   guide star acquisition, these initial exposures force the following science
   exposures in the middle or darkest part of each orbit (necessary, since one
   cannot ask for DARK-TIME or LOW-SKY in parallels).
4) Two 900 sec science spectra with STIS/CCD/G750L/52X2" or 52x0.5" slit (see
   below). We will actually start with one 1800 sec science exposure instead,
   and test if we can do the single-image column-wise CR-rejection realiably. 
   Otherwise, we will change back to 2x900 sec science spectra per orbit.
5) Place holder for the second (or more) science spectra per orbit if needed.
6) Two CCDFLAT's with the with STIS/CCD/G750L/52X2" or 52x0.5" slit.
7) Two more CCDFLAT's with the with STIS/CCD/G750L/52X2" or 52x2" slit
8) A second STIS/CCD Wavecal with STIS/CCD/G750L/52X2" slit to trace any   
   orbital drift in the wavelength calibration (important for accurate
   removal of low-level features in the Zodi spectrum that could mimic the
   H-edge signal).
9) Four BIAS frames for optimal bias-structure removal, and monitoring this
   bias level as a function of orbital position and temperature. 

Exposures 1--3 and 6--9 are take partially into occultation, or in any case
outside DARKTIME and outside most of the LOW_SKY window, and so force 4--5 into
DARKTIME. 

10) Four daily 1800 sec darks, or 28 weekly darks resulting in one weekly
   super-dark are taken standard by STScI. These we need to carefully analyze
   for optimal dark-current structure removal, hot-pixel removal, and tracking
   horizontal and  vertical CTE effects as a function of time.

(I) We need contemporaneous calibrations to each parallel orbit:\ This project
is a   relative measurement that must push the STIS calibration to its limits,
with a relative flat-field accuracy of   0.2--0.4\ reduce systematic errors in
the STIS spectra to an absolute minimum. As we did successfully in Cycle 8, we
will schedule  extra calibrations immediately before and after the two 900 sec
science spectra in each orbit, such that the science spectra end up in the
middle and therefore the darkest part of each orbit. The required automated
software for this exists. For each orbit, we need to take: (a) one 120 sec
direct exposure to locate obvious, spectrally contaminating objects to V=27
mag; (b) two 900 sec science spectra (or 4*450 sec to better control Limb
proximity); (c) four internal Tungsten or spectroscopic flats, also used for
fringe removal; (d) two wavelength calibrations; and (e) four bias frames. In
Cycle 8, we could attach all these calibrations automatically, without human
intervention. The standard STScI ``daily darks'' and weekly super-dark (28*1200
sec) are sufficient for our purposes.

DESCRIPTION OF DATA ANALYSIS PLAN  

Roles are divided among the PI (RAW), the co-I's in the STIS group ``STIS''=
NC, PP, BW), and analysis experts (RB, JM, RAW). RAW will coordinate all
efforts: sn  (1.a) Make the best possible darks and biases (NC, PP, RAW):\
Clipped-average calibration frames will be made for each visit to remove CR's
(c.f., W94a). Since the read-out and overhead times are not negligible (see
STIS Manual), the bias must be corrected for dark current, and the dark must be
properly bias subtracted. This is done through an iterative process, until a
consistent set of bias and dark stacks have been obtained for each visit. sn 
(1.b) Make the best possible flats (NC, PP, RAW):\ Flat-fields will be debiased
and dark-subtracted with the final bias and dark stacks.  All orbital flats in
a visit are be flat-fielded against each other to trace temporal variations and
to determine the optimal number of adjacent flats with which to flat-field the
STIS exposures. sn  (1.c) Hot pixel removal (STIS, RAW, W. Landsman):\ The
superdark is used in the CALSTIS Pipeline to subtract low-level dark-
structure, while daily darks are used to flag and remove the rapidly growing
number of hot pixels. The daily darks are not always close in time to allow for
proper interpolation to optimally remove all hot pixels. However, we always use
the darks taken   after the data in question so that never too few hot pixels
are removed. (Hot pixels grow with time due to the heavy on-orbit cosmic-ray
flux, but only a fraction disappear after the monthly anneal). sn  (1.d) Fringe
removal STIS, RAW, E. Malumuth):\ Although fringing has not been detected in
our Cycle 8 stack --- since the low resolution of the spectra through the 52*2"
slit smears out all fringes --- it may be visible in our deeper stacked data
set or in the higher resolution spectra we will obtain with the 52*0.5" slit.
If necessary, the cross-correlation routines demonstrated by Malumuth Etal
(2000) will be used to remove fringing.   These calibration data and IDL
routines that push STIS to its limits will be of use to other GO's and made
available publicly.  mn  (2.a) Determine the STIS Sky spectrum as a function of
Ecliptic and Galactic latitude and Longitude (RAW, PP).\ First, we sort the
~426-orbit Cycle 8+10 orbits into wide (~20degrees*20degrees) bins of similar
Ecliptic and Galactic latitude. There are ~100 such bins on the sky, and each
bin will contain about ~4 parallels on average (spread over 2--4 different
fields, a minimum to reject outliers). Next, we will make a spectral stack as
in Fig. 4 for each latitude bin, by making a carefully weighted clipped average
(using one-sided 2.5-Sigma clipping) of the spectral images in that bin. This
to first order removes all discrete objects that may have leaked into the
long-slit. If necessary, we enlarge the bin-size to include a sufficient number
of spectral images. sn  (2.b) Construction of the 1- dim STIS Sky spectrum for
each bin (RAW, PP, RB).\  Next, we collapse the STIS spectral stacks in each
latitude bin along the slit over the ~1000 usable spatial pixels (excluding the
slit support structures in Fig. 4), avoiding obvious bad areas or faint objects
leaking into the slit that were not completely removed when median filtering
the images. (The latter are identified from the direct finder exposures at the
start  of each orbit). It will be fluxed with a template zodiacal light
spectrum to emphasize non-zodiacal features in the background. 

(3) Removal of foregrounds (RB, RAW).\ Next, we remove from the spectral stack
in each latitude bin the best spectral model of the following foreground
components, after properly rescaling them to match the observed amplitude in
each spectral stack. This assures that variations in amplitude of the Zodiacal
background with Ecliptic latitude, and any variation in the smooth DGL
component with Galactic latitude, are properly removed. The expected foreground
optical--near-IR contamination consists of three main components, in order of
decreasing brightness:

(A) Zodiacal; (B)  Diffuse Galactic Light (DGL); and (c) Extragalactic
Background  Light (EBL). sn  (3.a) The Zodiacal component (RB, JM, RAW).\ The
zodiacal (~eqsolar) spectrum is mostly featureless over the wavelength range of
interest, except for perhaps the Ca feature at 0.89Mu. It is known at very high
S/N (>> 1000; http://garnet.stsci.edu/STIS/models/G2V.gif). Zodiacal dust
particles with sizes <1Mu may not change the high frequency part of the solar
spectrum around 1Mu drastically, but they can slightly modify the global
Zodiacal spectral gradient due to non-grey scattering. This we will quantify
through a careful comparison of the Zodiacal spectrum to the known solar
spectrum. We will separate the Zodiacal spectrum from the much fainter DGL
spectrum, using the lower latitude parallels (i.e. b~20--35degrees) which have
a quite different Zodi/DGL ratio. A slightly reddened solar spectrum will be
subtracted from each STIS spectrum, after appropriately scaling to avoid
oversubtracting, following Bernstein Etal 2000b). sn  (3.b) The DGL Component
(RB).\ Possible high spatial frequency structures in the DGL are a concern at
SB- levels of ~26--27 mag/arcsec^2 (Szomoru & Guhathakurta 1998; Guhathakurta &
Tyson 1989). The Cycle 8 parallels were selected at high Galactic latitudes
(\EBminV 0.01 and low \NH), and so the DGL there should be rather faint (\cge
28-- 30\magarc), as the deepest surveys at high latitude have shown (e.g.,
Tyson 1988, Williams Etal 1996). Since the DGL likely bears the spectral
signatures of early-type (O and B) stars in our Galaxy, we do not expect a
large spectral feature at 0.6--1Mu from the stellar population that causes the
DGL. We will fit a smoothed OB star template to match the DGL spectra from the
lower latitude fields to locate any suspect features, and make improved DGL
spectra to subtract from the high latitude fields. The EW of Zodiacal features
in the higher resolution STIS/G750M 0"pt 5 slit spectra will be used to help
isolate the different DGL components in each field (Bernstein Etal 2000b). sn 
(3.c) The EBL component RB).\ The EBL should be at levels fainter than I~eq27.5
mag/arcsec^2 (Bernstein Etal 2000a), because the galaxy counts are now known to
permanently converge with a sub- critical slope Alpha<=0.4 for B>= 25--26 mag
(Metcalfe Etal 1996) and for I>= 24--25 mag (Williams Etal 1996). The best
estimate of the ~ 1Mu EBL by Hauser Etal (1998) amounts to 4.7* 10^-20
erg/cm^2/s/Angstrom/arcsec^2 and Bernstein Etal 2000) similarly amounts to
SB(1Mu)~27.5 AB-\magarc. Since the EBL is featureless (\S 2.a) and faint, no
EBL template needs to be subtracted from the collapsed STIS spectra in order to
find a Hydrogen reionization edge. mn  (4.a) Construction of the final spectral
stack (RAW, RB).\ After subtraction of the best model Zodiacal and DGL
components from the STIS spectra in each bin, we will make a carefully
weighted clipped average (using one-sided 2.5-Sigma clipping) of all spectral
images across the sky. This should further remove any discrete objects that may
have persisted in any of the long-slit spectra. The end-result is a ~426 orbit
spectral stack (a la Fig. 4), but with the Zodiacal and DGL components removed.
sn  (4.b) How to search for the Lyman Hydrogen reionization edge  in the STIS
spectra (RAW, RB, JM).\ Next, we will collapse all 1000 spatial pixels (~0"pt
05 each) along the slit of the final stack into one 1-dim STIS sky spectrum
(c.f., Fig. 4). We will see if any significant step survives in this collapsed
STIS spectrum after we subtract the best fit scaled templates of the Zodiacal
and DGL spectra, and check if any step is close to a weak known feature in the
Zodiacal spectrum (as compared to the solar spectrum), or to an atmospheric O-I
line.  We will sum large wavelength swaths at wavelengths both shorter and
longer than any visible Ly-alpha edge. One advantage is that the   frequency
direction of the step is known. We move these swaths in a ``sliding rule''
manner to find the most significant edge in the collapsed sky spectrum, if such
an edge is not directly obvious from the data. We will autocorrelate clean
slices of the spectrum to find the step if it is buried in the data.
