The Aperture should be UVIS2-C1K1C-CTE. I have applied an offset of 7" on both X and Y from that position, as I would like a bit more impact parameter about my targets. The telescope orient was chosen to minimize occurence of moderately or severly saturated objects in the field. Object EG3 added a CRSPLIT to the F606W exposures (unlike all the other exposures), because there is a bright field galaxy very close to the target, and saturation was a concern. CR mitigation shouldn't be an issue given the dithers (there are a minimum of 4 exposures per field/filter combo. In accordance with the recommendation, I have broken the 5 orbit F390W exposures into a 2 orbit and 3 orbit visit. If it is possible to have them all in one visit, that would be preferred, but not essential. Thanks!

Receipt: # 14160-2 ----- Attempting Submission 4 (Wed Jul 22 16:46:45 GMT 2015) ----- If I understand the warning correctly, it is that the target is not at the center of the dither (because I applied offsets of 7 arcseconds in X and Y from the default aperture position). I am not concerned about this from a science point of view, as the dither was meant to mitigate CR and to fill the chip gap. A 100 million-fold increase in the measured sizes of neutral gas reservoirs in the early Universe The damped Lyman alpha systems (DLAs, log (NHI) >= 20.3) seen in absorption toward distant quasars have been studied for over 40 years, yet two of their most fundamental properties, namely their size and their mass, have remained elusive. Sightlines to QSOs probe only a fraction of a parsec of the area of the DLAs. Although methods currently exist to measure DLA spatial extents, they trace only their star forming regions (direct imaging), only their rest frame optical extents (IFU searches), or offer only pencil beam piece-wise sampling (close background quasar pair spectra). In this proposal, we present a new technique to directly constrain the size of the neutral hydrogen gas absorption in the DLA via their detection in the spectra of background galaxies. We have a pilot sample of 3 DLAs seen in the spectra of z~3 galaxies, and require HST+WFC3 images to obtain the spatial extent of these galaxies. Doing so will increase our knowledge of the spatial extent of DLA gas by a factor of at least 10^8 over present measures. We will obtain imaging in 5 F390W orbits and 2 F606W orbits for 3 target galaxies EG1, EG2, and EG3 using WFC3+UVIS QUASAR ABSORPTION LINES AND IGM 12 false false false false SUPPORTED GALAXY HIGH REDSHIFT GALAXY J2000 J2000 GALAXY HIGH REDSHIFT GALAXY J2000 J2000 GALAXY HIGH REDSHIFT GALAXY J2000 J2000 WFC3/UVIS Imaging No No F390W WFC3/UVIS Imaging No No F606W WFC3/UVIS Imaging No No F390W WFC3/UVIS Imaging No No F606W WFC3/UVIS Imaging No No F390W WFC3/UVIS Imaging No No F606W POS-TARG MOSAIC DITHER 4 2.414 WFC3-UVIS-DITHER-BOX false 81.785 true 0.112 0.173 2 85.759 POS-TARG WFC3-UVIS-GAP-LINE 23.884 1
