The list of Investigators does not match the STScI records for this program.0----- Attempting Submission 1 (Wed Jan 26 19:40:39 GMT 2022) -----The ULLYSES CO-I list changes along with the implementation team membership.ULLYSES M-Type T Tauri Survey Stars in Lupus III: Part 4The 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)
Additional details about the scientific motivation and technical implementation strategy of the ULLYSES observations can be found at http://www.stsci.edu/stsci-research/research-topics-and-programs/ullyses. The ULLYSES program is based on the recommendations of a working group led by Sally Oey; the full text of that group's report can be found at http://www.stsci.edu/files/live/sites/www/files/home/stsci-research/research-topics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf.

Flare screening:
Screening for magnetic flares was done using the cleartargets.py script in the ullyses_tech python repository. Both the input file used, sz100_104_flare_calc_inputs.csv, and the output produced, sz100_104_flare_calc_results.xls, are in the STScI Box folder ullyses_tech/ullyses_proposals/survey_c29/16858/ which should be accessible to the CS reviewer. The spectral energy distribution for each of the adopted flares should are also in that folder, and can be input into the ETC.
For SZ100, we treated the flare as if from a M5.5 dwarf with V=16.624.
For SZ104, we asssumed a M5 dwarf with V = 16.8.
For both stars, an intevening neutral hydrogen column of log n(HI) = 19.27 was adopted;
this is equivalent to Av=0.01 for a typical Galactic siteline and should be a conservative lower limit for these stars at their distances of 137 pc and 165 pc.
Results for the needed observing modes are reported in the file sz100_104_flare_calc_results.xls and show no issues.
In particular for both stars, COS imaging observations with NUV PSA MIRRORB produce peak local rates under 80 counts/pixel/second, which passes the flare screeing required for this mode, allowing PSA/MIRRORB to be used for our target acquistions.
Note that our adopted V magnitudes for these are significantly fainter than given in SIMBAD, but review of the literature suggests the results quoted in SIMBAD are not reliable, and that signicantly fainter values are instead correct. The SIMBAD V magnitude of 15.43 for SZ100 and 15.25 for SZ104 were both taken from Merin et al, 2014, but Merin et al did not do their own B or V photometry, instead taking those values from the Naval Observatory Merged Astronomical Data Set (NOMAD) catalog, (https://vizier.cds.unistra.fr/viz-bin/VizieR?-source=I/297), which for both SZ 100 and SZ104 points in turn to an unpublished USNO "YB6" catalog for which very little documentation is available as the ultimate source for both the B and V values that were subsequently quoted in SIMBAD and many other publications for these stars.
For SZ100 we instead adopt V=16.624 from https://www.aavso.org/download-apass-data, and also note a measurement of V=16.87 from Sartori et al 2003. In additio,n interpolating V using its relation with Gaia G and Bp-Rp yields an estimate of V=16.59. Since all of these values are close, we are confident that the YB6 catalog V value is not correct for the typical state of this target. Note that the same problem affects the quoted B magnitudes in SIMBAD.
For SZ104, Satori et al report V=16.91, while interpolation of the Gaia measurements implies V about 16.8. We have adopted this latter value for our estimates.
-------------------
Choice of Models for ETC calculations
The scaled accretion models were created from K stars and significantly overestimate the continuum flux in the optical.
However it is assumed that the emission lines and the continuum flux below the Balmer jump are well represetnted by the scaled models.
So for each star, we will use 3 ETC models for our estimates.
For both these targets, the nominal Av is zero, but for S/N calculations we will adopt an extra 0.5 mags of Av.
For STIS S/N continuum measurements, we will use a Phoenix photospheric model, with an extra 0.5 mags of Av, normalized to the observed V magnitude
Sz-100_M5.5_scaled_pAV0.50_sed.fits
SZ-104_M5_scaled_pAV0.50_sed.fits
G430L observations were limited to one orbit, even if they don't quite meet the nominal S/N requirements at 4000A. The S/N increases dramatically at longer wavelengths, and so these spectra will have very good S/N at most wavelengths.
For UV S/N calculations, we will use the usual accretion models based on the scaled accretion flux, but with an added 0.5 mags of Av.
sz100_lya2_etc_scaled_pAV0.50_sed.fit
sz104_lya2_etc_scaled_pAV0.50_sed.fits
For BOP and saturation calculations, we will assume 4X the default accretion model, and we will not include the extra 0.5 mags of Av, as for these systems in particular, it is not clear that this is appropriate.

Comparison with more recent measurements suggests YB6 values for these stars are not reliable, so instead we have adopted recent values obtained from APASS at https://www.aavso.org/download-apass-data. Note also V=16.87, V-Ic=3.63 from Sartori et al 2003, which are consistent with our adopted values; Also, interpolating observed Gmag as a function of Bp-Rp imples V = 16.59, very close to the APASS value.
