This target is not used in this proposal. Removed all phase requirements Changed CCD gain back to 4 for the external G430L/G750L exposures Some cleanup in the comment lines. ----------------------- Hello Tricia: I've fixed the betweens to better match the TESS timing and changed the STIS G430L and G750L to GAIN=1. Charles Hello Tricia: As you saw in the email, I'm still waiting for the detailed STIS review, but it should hopefully be in essentially final form, as the STIS observations are much less complex than the COS ones. Two targets have ORIENT constraints, but in these cases the restrictions on scheduling are relatively modest, losing only a few days off either end of the TESS window (it was the one in 16114 that had more severe constraints). Three of the COS visits and one of the STIS ones also need to use an offset target for the target acquisition. The current proposal requires 23 orbits, in agreement with what appears to be in the database. Charles -433960883 ----- Attempting Submission 3 (Mon Sep 28 16:13:33 GMT 2020) ----- ----- Attempting Submission 4 (Wed Oct 14 03:13:17 GMT 2020) ----- ----- Attempting Submission 5 (Tue Oct 27 17:01:18 GMT 2020) ----- An unused alternate offset target is included in case the one currently selected for that target can't be used due to guide star issues. The 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 + c1611 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=15/6-pix-resel at the peak of the line COS/G160M/c1611: C IV 1549 +- 1 A -- S/N=30/6-pix-resel at the peak of the line 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. To obtain near simultaneous coverage, all visits to a given target should be grouped within 1 day. The visits in this proposal are all constrained to occur between 19 November and 17 December 2020 to be simultaneous with planned TESS observations. We also wish to attempt to obtain simultaneous coverage with telescopes of the LCOGT network. Unfortunately, this network has an approximately 3 hour gap in coverage for the Orion targets due to the lack of an observatory at an appropriate longitude. We will therefore add a period and a phase constraint to these observations to prevent the HST observations from being scheduled during this daily gap. The period when the Orion stars can be observed by this networks starts when they reach ~ airmass of 2 from the Sutherland observatory in South Africa, and ends about 21 hours later due to the start of morning twilight in Siding Springs Australia. If we take the limits from http://catserver.ing.iac.es/staralt/ for the times we can observe our Orion targets we get roughly 19 Nov: start 20:30 (airmass=2 Sutherland) end: 24h+17h:2m1 (morning twilight Siding Springs) -> window length about 20.84 hr 17 Dec: start 19:21 (evening twilight Sutherland) end 24h+17h:1h5 (morning twilight Siding Springs)-> window length about 21.92 hr We will approximate the times of allowed coverage by assuming a daily 21.1 hour window with a start time of 21:25 UT on 17 November that slips earlier by 2.5 minutes each day (we allow 5 minutes for the TA which does not require simultaneous coverage). For our Orion targets, the 17 November start time corresponds approximately to HJD = 2459173.3554330356, with a variation of a minute or less between the different targets. The period of the phase window is then 1 - 2.5/1440 = 0.99826388889 days, and the allowed phase window for the TA exposure to start then runs from phase 0 to an end phase of 0.852839, 0.786724, or 0.720608, for 1, 2, or 3 orbit visits respectively. To calculate these phase window lengths, we have assumed that the visits will lay out as shown in APT, but to ease HST scheduling constraints we do not actually force them to be non-interuptible sequences. This may mean that some visits run longer than we have assumed, and some exposures may extend into the period when LCOGT cannot observe them. At each TESS perigee, there are two LAHO (low-altitude housekeeping operations) contacts. TESS science observations stop 10 minutes before the beginning of the first LAHO and resume 5 minutes before the end of the second LAHO. Times of LAHO contacts are posted on the TESS operations calendar at https://calendar.google.com/calendar/b/0/r/week?cid=a21va3YydDM0dmpsc2w2Ymw2Z29vdWE2OGNAZ3JvdXAuY2FsZW5kYXIuZ29vZ2xlLmNvbQ approximately 3 months in advance. We will require that our visits start at least 45minutes prior to the start of any gap in TESS operations. For TESS sector 32, LAHO Passes (1) 19-Nov-2020 08:45-13:45 start - 5m before LAHO end (2) 02-Dec-2020 10:45-15:45 stop - 10m before LAHO start (3) 03-Dec-2020 05:45-10:45 start - 5m before LAHO end (4) 16-Dec-2020 17:45-22:45 stop - 10m before LAHO start TESS start/stop times 19-Nov-2020:13:40 to 02-Dec-2020:10:35 03-Nov-2020:10:40 to 16-Dec-2020:17:35 Constrain end of HST BETWEENs to be 55m, 2h30m, and 4h5m before TESS end for 1, 2, and 3 orbit visits to allow HST to complete before TESS end HST-1 orbit: subtract 50 minutes from end times 19-Nov-2020:13:40 to 02-Dec-2020:09:40 03-Nov-2020:10:40 to 16-Dec-2020:16:40 HST-2 orbit: subtract 2h25m from end times 19-Nov-2020:13:40 to 02-Dec-2020:08:05 03-Nov-2020:10:40 to 16-Dec-2020:15:05 HST-3 orbit: subtract 4h from end times 19-Nov-2020:13:40 to 02-Dec-2020:06:30 03-Nov-2020:10:40 to 16-Dec-2020:13:30 M-dwarf flares. Observed U fluxes in T Tauri stars are strongly enhanced by the accretion flow and so cannot be used to directly calculate expected flare sizes based on observed dwarf delta U observations. Instead we use the V magnitude and infer a U mag appropriate for the adopted spectral type and then apply the flare rules. We assume results scale with the bolometric luminosity of the star, and so can be calculated as if it was a dwarf at the effective distance appropriate for the observed V magnitude. For results for the M type CVSO stars see cvso_mstar_flare_results.xls in the box folder. There we input the observed V, together with a B mag that forces selection of the desired spectral type, and otherwise does the calculation as specified in the relevant COS/STIS ISRs. 0 false SUPPORTED STAR T TAURI STAR PRE-MAIN SEQUENCE STAR NO CVSO-104 : Haro 5-64A, J05320638-0111000 Region: Ori OB1b Simbad: http://simbad.u-strasbg.fr/simbad/sim-id?Ident=Gaia+DR2+3217634157789741952&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id Target coordinates are from Gaia DR2.

For this star the U band flux is only 1.36x our nominal case, while the observed peak of the C IV 1554 line is only about 1/3rd of the nominal scaling (or about 1/12th the 4X scaled spectrum). So this suggests the 4x spectrum is probably a significant overestimate of the flux to be expected in Lyman alpha.
