The list of Investigators does not match the STScI records for this program.1st submission; program implementation complete; ready for CS review - Debopam Som752815023----- Attempting Submission 1 (Fri Jan 21 23:15:14 GMT 2022) -----List of investigators has been updated internallyULLYSES M-Type T Tauri Survey Stars in Lupus III: Part 1The Space Telescope Science Institute (STScI) Director has decided to devote up to 1000 orbits of Director's Discretionary time in observing Cycles 27-29 to a new Hubble Ultraviolet Legacy program focused on star formation and associated stellar physics. This new program, ULLYSES (UV Legacy Library of Young Stars as Essential Standards), will provide a UV spectroscopic reference sample of young (< 10 Myr) high- and low-mass stars. It will target over ~150 OB stars in the Magellanic Clouds and lower metallicity galaxies in the Local Group, and ~40 T Tauri stars and brown dwarfs in the Milky Way. In addition, ULLYSES will monitor 4 typical T Tauri stars over different rotational phases through at least three rotation periods, and over timescales of months to years. The resulting library will provide template spectra of massive stars at metallicities substantially below the well studied, while the low mass sample will cover a wide range of ages, accretion rates, and masses, including objects down to well below 0.5 M_sun. The legacy of this large UV dataset on the first 10 Myr of stellar evolution will be enhanced by complementary datasets obtained by the scientific community. In addition to the core goals of the program related to stellar astrophysics of low and high mass stars, this data will also enable exciting science in the fields of ISM, CGM, jets, and exoplanets. ULLYSES will be modeled after the Frontier Fields program: all data obtained will be non-proprietary. The implementation team at STScI is developing high-level science data products and a sophisticated database and website for disseminating data from the ULLYSES program and ancillary datasets for the ULLYSES target sample from space and ground-based facilities.This proposal includes a subset of the low mass ULLYSES survey stars. Each target will be observed with the COS c1291 + c1589 + c1623 settings, as well as with STIS G230L, G430L, and G750L. All observations will normally be constrained to occur within 1 day.
Signal-to-noise requirements used to determine the desired exposures times were defined as follows:
COS/G130M/c1291: N V 1239 +- 1 A -- S/N=10/6-pix-resel at the peak of the line
COS/G160M/c1589: C IV 1549 +- 1 A -- S/N=20/6-pix-resel at the peak of the line (combined c1589 & c1623)
COS/G160M/c1623: C IV 1549 +- 1 A -- S/N=20/6-pix-resel at the peak of the line (combined c1589 & c1623)
STIS/G230L/52X2: Mg II 2800 +-15 A -- S/N=20/2-pix-resel at the peak of the line
STIS/G430L/52X2: continuum average 4000 +-5 A -- S/N=20/2-pix-resel (2 reads)
STIS/G750L/52X2: continuum average 5700 +-5 A -- S/N=20/2-pix-resel (2 reads)

For the M dwarf check of Sz 97, we use A_V = 0.3, reported by Mortier et al. (2011, MNRAS, 418, 1194); henceforth M11. This is more reasonable than the A_V = 0.0 reported by Alcala et al. (2014, A&A, 561, A2); henceforth A14. Both M11 and A14 compare spectra of Sz 97 to templates to derive A_V. M11 use a field dwarf as a template, which almost certainly has A_V = 0. A14 use Sz 94 as a template and do not seem to allow for the fact that it may have A_V > 0. This does not affect exposure time estimates, since these were conservatively calculated assuming A_V = 0.5.

The offset acquisition is performed on GAIA-DR2-5997393346040677504 which is 35.4" away from sz-117. Information on this target is not available on SIMBAD. However, the GAIA archive reports G = 15.68 and Bp-Rp (observed) = 1.927.
The Starhorse catalog (Anders+2019) models Av = 4.6, E(B-V) = (Av/3.1) = 1.48, Teff = 9668.5, logg = 4.2, Fe/H = -0.3, Bp-Rp (de-redenned) = -0.102. These categorizes the star as SpT A0V
Interpolated photometry for target SpT A0V:
V = 15.7 from G = 15.68.0 with G - V = 0.01
B = 15.7 from V = 15.7 with B - V = 0.00
We also consider the scenario that the target is a redenned O star instead and proceed to verify safe observations:
Using the apparent Bp-Rp = 1.927 and colors form https://innerspace.stsci.edu/display/ULLYSES/STIS+TA+vs+broad-band+photometry+including+Gaia, the interpolated photometry for O3V scenario (screening):
V = 16.8 from G = 15.68 with G - V = -1.088
B = 18.1 from V = 16.8 with B - V = 1.342
The estimated E(B-V) in this scenario is (B-V) + 0.31 = 1.65, very similar to what reported in the Starhorse catalogGAIA-DR2-5997393346040677504J2000SpT=A0V; A_V = 4.6; G = 15.68; Bp - Rp (observed) = 1.9; Bp - Rp (de-redenned) = -0.102; B = 15.7START TAURI STARPRE-MAIN SEQUENCE STARNOSZ-98V1279-SCOJ2000SpT=K7; A_V=1.00; B=14.80; V=13.52; J=9.530Timing link suitability includes constraints ([Group (1C 1D 1E 1F 1S) Within 2.0 days])The scheduling data was generated by CASM 29.2.CASM was run in Phase II mode./Users/dsom/Box/ullyses_tech/ullyses_proposals/survey_c29/16855/OP-cache/ULLYSES_16855-v1C.xmlvstatus; 1C; SSTC2DJ161243.8-381503; P/COS approved for submission; P/DS 19/01/22 ; intrev: complete ; P/WF 19/01/22

The offset acquisition is performed on GAIA-DR2-5997393346040677504 which is 35.4" away from sz-117. Information on this target is not available on SIMBAD. However, the GAIA archive reports G = 15.68 and Bp-Rp (observed) = 1.927.
The Starhorse catalog (Anders+2019) models Av = 4.6, E(B-V) = (Av/3.1) = 1.48, Teff = 9668.5, logg = 4.2, Fe/H = -0.3, Bp-Rp (de-redenned) = -0.102. These categorizes the star as SpT A0V
Interpolated photometry for target SpT A0V:
V = 15.7 from G = 15.68.0 with G - V = 0.01
B = 15.7 from V = 15.7 with B - V = 0.00
We also consider the scenario that the target is a redenned O star instead and proceed to verify safe observations:
Using the apparent Bp-Rp = 1.927, the interpolated photometry for O3V scenario (screening):
V = 16.8 from G = 15.68 with G - V = -1.088
B = 18.1 from V = 16.8 with B - V = 1.342
The estimated E(B-V) in this scenario is (B-V) + 0.31 = 1.65, very similar to what reported in the Starhorse catalog
The nominal ETC calculation uses PSA/MirrorA ACQ/IMAGE with Castelli-Kurucz A0V (T_eff = 9549K, logg = 4.2), normalized to Johnson V = 15.7 Vegamag with E(B-V) = 1.48 (ETC ID 1684051, B.P = 0.889). The exposure time of 255.2 s is for S/N = 40 (double of the PSA recommended S/N of 20) to account for target faintness.
The O3V screening calculation uses PSA/MirrorA ACQ/IMAGE with Castelli-Kurucz O3V (T_eff = 45000K, logg = 4.5), normalized to Johnson V = 16.77 Vegamag with E(B-V) = 1.65 (ETC ID 1684055, B.P = 1.408)
BOT reports the OFFSET target as unsafe for the acquisition with PSA/MirrorA assuming a O5V SED but without any extinction applied. We have shown that the acquisition should be safe for a O3V with extinction E(B-V) = 1.65 which is estimated from the observed GAIA colors.ETC exposure time of 1371.3 s for G130M (both FP-POS combined) is increased to a total exposure time of 3430 s

Worst-case ETC run (1683335) gives 0.09 cts/s in brightest pixel and buffer time of 3044 s
M dwarf flare ETC run (1683336) gives 0.851 cts/s in brightest pixel which exceeds normal bright limit but is under the M dwarf limit.

The offset acquisition is performed on SZ-98 which is 26.6" away from SZ-97, due south-east. SZ-98 itself is a ULLYSES T-Tauri target, being observed in Cycle 29 as part of program 16854. SZ-98 is vetted as a SpT K7 star with Av = 1.00, E(B-V) = (Av/3.1) = 0.32, B = 14.80, V = 13.52 and J = 9.530.
Program 16854 acquire SZ-98 using ACQ/IMAGE with BOA/MIRRORA but our offset acquisition uses PEAKXD/2950/B + PEAKD/2950 to acquire this star since COS NUV spectroscopic acquisition was determined to be more efficient (better S/N delivered with in shorter time; please see ~/Box/ullyses_tech/ullyses_proposals/survey_c29/16855/sz-117/sz97_acq_strategies.xls)

)true20Due to M dwarf rules, direct COS imaging or spectroscopic acquisition is impractical and and an offset acquisition is to be performed.
The offset acquisition is performed on SZ-98 which is 26.6" away from SZ-97, due south-east. SZ-98 itself is a ULLYSES T-Tauri target, being observed in Cycle 29 as part of program 16854. SZ-98 is vetted as a SpT K7 star with Av = 1.00, E(B-V) = (Av/3.1) = 0.32, B = 14.80, V = 13.52 and J = 9.530.
Program 16854 acquire SZ-98 using ACQ/IMAGE with BOA/MIRRORA but our offset acquisition uses PEAKXD/2950/B + PEAKD/2950 to acquire this star since COS NUV spectroscopic acquisition was determined to be more efficient (better S/N delivered with in shorter time; please see ~/Box/ullyses_tech/ullyses_proposals/survey_c29/16855/sz-117/sz97_acq_strategies.xls)
We use the CTTS template to perform the ETC calculations:
For S/N calcs, A_V = 1.5 is used instead of nominal A_V = 1.0; see sz98_lya2_etc_scaled_pAV0.50.txt
For BOP calcs, nominal A_V is used and the spectrum is scaled up by 4x; see sz98_lya2_x4.00_etc.txt

The nominal ETC exposure time of 7.53 s (to reach the recommended S/N of 40 with PEAKXD/2950/B) is quadrupled to 30.2 s to guard against target dimming.

)true20Nominal ETC run gives 0.09 sec for S/N = 40
Worst-case ETC run (1683755) gives saturation in 5.62 sec
M dwarf flare ETC run (1685527) gives saturation in 1.40 sec
Used a hybrid model: CTTS template below 3700 A; M4 dwarf scaled to B = 17.11 above 3700 A
For S/N calcs, A_V = 0.5 is used instead of nominal A_V = 0.0; see sz97_lya2_etc_scaled_pAV0.50_M4phot.txt
For BOP calcs, nominal A_V is used and both components are scaled up by 4x; see sz97_lya2_x4.00_etc_M4phot.txt
Above SEDs and an IDL program to make them are in ~/Box/ullyses_tech/ullyses_proposals/survey_c29/16855/sz-97/seds/
For M dwarf flaring, see ~/Box/ullyses_tech/ullyses_proposals/survey_c29/16855/sz-97/mdwarf
For the M dwarf check of Sz 97, we use A_V = 0.3, reported by Mortier et al. (2011, MNRAS, 418, 1194); henceforth M11. This is more reasonable than the A_V = 0.0 reported by Alcala et al. (2014, A&A, 561, A2); henceforth A14. Both M11 and A14 compare spectra of Sz 97 to templates to derive A_V. M11 use a field dwarf as a template, which almost certainly has A_V = 0. A14 use Sz 94 as a template and do not seem to allow for the fact that it may have A_V > 0. This does not affect exposure time estimates, since these were conservatively calculated assuming A_V = 0.5.ETC exposure time (0.40 cts/s in brightest pixel) of 208.4 s was increased ~150% to 525 s
Worst-case ETC run (1683819) gives 3.90 cts/s in brightest pixel and buffer time of 740 s
M dwarf flare ETC run (1685524) gives 10.9 cts/s in brightest pixel
Buffer time set to just under half the exposure time
