Receipt: # 762-13 The same comments apply as of Sept 29 2017. This is a resubmission to repair duplicates from the original Phase II. The preparation of Phase II went fairly smoothly, the main challenge was that we are coordinating these observations with a JWST GTO program, and had to calaculate many of the roll angle restrictions by hand. It would be helpful if the Aladdin tool had some functionality for cross-comparing HST and JWST focal planes for similar alignment tasks. For example, if you could load a JWST Phase II (or Phase I!) into a buffer and see how particular alignment combinations affect the schedulability of both telescopes. We found that scheduling constraints for JWST can be restrictive in ways that are not immediately obvious, and I'm guessing other users may see the same in the near future. This is not a criticism though, just a suggestion for future improvement. Our overall experience was good. 930020439 ----- Attempting Submission 1 (Thu Jul 20 15:48:44 GMT 2017) ----- ----- Attempting Submission 2 (Fri Sep 29 09:09:01 GMT 2017) ----- Galaxies in the Diffuse Baryon Field Approaching Reionization: A Joint Study with JWST, HST, and Large Telescopes Our team is conducting a dedicated survey for emission-line galaxies at 5 < z < 7 in six fields containing the best and brightest z > 6 quasars, using JWST/NIRCAM's slitless grism in a 110 hour GTO allocation. We have acquired deep near-IR spectra of the QSOs, revealing multiple heavy-element absorption systems and probing the HI optical depth within each object's survey volume. These data will provide the first systematic view of the circumgalactic medium at z > 4, allowing us to study early metal enrichment, correlations of the intergalactic HI optical depth with galaxy density, and the environment of the quasar hosts. These fields generally do not have deep multicolor photometry that would facilitate selection of broadband dropout galaxies for future observation with JWST/NIRSPEC. However during long spectroscopic integrations with NIRCAM's long channel we will obtain deep JWST photometry in F115W and F200W, together with F356W for wavelength calibration. Here we request 30 orbits with HST/ACS to acquire deep optical photometry that (together with the JWST IR bands) will constrain SED models and enable dropout selection of fainter objects. For lower redshift objects the rest-UV ACS data will improve estimates of star formation rate and stellar mass. Within a Small-GO program scope we will obtain sensitivity similar to CANDELS-Deep in all six fields, and approximately double the size of our galaxy sample appropriate for JWST/NIRSPEC followup at redshifts approaching the reionization epoch. The goal of this proposal is to obtain deep imaging in F775W and F606W for selection of faint dropout galaxies (AB=26-27) in six fields that will be observed with JWST / NIRCAM grism for a galaxy survey around bright quasars. We were awarded time for F775W but not F606W. After accounting for existing archival F775W, we will observe a total of five target fields over 18 orbits in this single filter. Three targets require 4 orbits apiece to achieve our depth requirements (for selection on the blue side of a photometric break). The remaining two fields (SDSS1148 and J0100) each require 3 orbits because the archive already contains a single orbit in F775W. Our observing strategy is heavily influenced by constraints imposed from the JWST GTO survey, in the following ways. 1) Dithers: the most valuable region is a 43" box centered upon the quasar, which we wish to be in the center of the field. This area will be imaged to ultra-deep levels with JWST in the infrared, and contains high-value targets for study of the early CGM. Our dither strategy is designed to avoid placing the ACS/WFC chip gap anywhere within this box. We achieve this by executing a +Y POS TARG offset of 11 arcsec to move the object ~21" from the chip gap initially. We then execute a 4-point dither where the first two points have sepearation just large enough to span the gap, and the second two are offset in -Y (POS TARG) by ~45" (effectively dithering the gap to the other side of the target). This leaves areas of shallower exposure depth on the outskirts of the field, but this is acceptable to get continuity and depth near the center. The dither angles and distances are derived from offsets used in the COSMOS survey (Koekemoer et al 2007, ApJS 172:196), but rescaled to cover a larger distance in Y while still sampling +/-0.5 pixels for drizzle purposes. We understand and accept that the distances will not be exact because of optical distortions. 2) Roll angle/orientation restrictions: It is critically important for our data to be taken so that the cardinal directions of the ACS sensors are aligned with the corresponding orientation of JWST/NIRCAM. This aligns the regions of greatest exposure depth, where we will select targets for NIRSPEC followup. We have accordingly planned our ACS Phase II in conjunction with our JWST Phase II preparation. At the time of Phase I we did not have information about roll angle restrictions imposed by JWST, which turn out to be somewhat severe. For our targets near the celestial equator (SDSS1030, SDSS0148, P159-02) our preferred roll angles (driven by JWST) could not be scheduled for ACS. For these fields we are forced to rotate 90 degrees from optimal, which loses field coverage but is the next most desirable configuration. At these angles the schedulability is high for ACS. For our more Northern targets (SDSS1148, J0100) it was possible to schedule ACS at the proper orientation to align with JWST, although over a somewhat limited window. The tight tolerances on allowable orient angles is almost entirely driven by the scheduling requirements for JWST and coordination of programs across the observatories. For the latter two targets, we included four roll angle envelopes to relax scheduling constraints for ACS but in both cases we have a significant preference for scheduling in one of the first two blocks (for optimal alignment with JWST).
