Be very careful mixing POS TARG and Center_Pattern = YesDear all,
We completed the Phase II of this proposal, specifically following indications on CTE effect mitigation strategy for WFC3/UVIS observations,
as suggested by the CS, and specified in the Instrument Handbook and the recent ISR 2020-08. We added POSTFLASH =15 to reach a final e- background level ~20e-.
This triggered a warning in the APT, given the level expected was ~12e- , but we submit the Phase II material nevertheless.
[07-10-2020] We modified the Special Requirements ORIENT following the advice from the TTRB (see Change Request 91796.
We also add a sub-pattern for better PSF sampling in WFC3/IR observations, as suggested by Contact Scientist.
[07-12-2021] Due to scheduling problems (missing guide stars), we removed visits (4) - (9) and added visits (10) - (27). Now, each new visit is composed of one orbit only.
In order to account for this, we slightly changed the observations strategy (patterns). For more details see Proposal informations.
[21-12-2021] We followed additional suggestions regarding the observing strategy with WFC3-IR and WFC3-UVIS, and changed visits (10)-(27) accordingly.
For more details see Proposal informations.1399764346----- Attempting Submission 1 (Mon Jun 29 08:34:26 GMT 2020) -----

----- Attempting Submission 4 (Tue Dec 21 10:06:59 GMT 2021) -----We added a POSTFLASH =15 in all our observations with WFC3/UVIS, to reach a final background level of ~20e-,
greater than the recommended 12e- level.
This was done following the very recent indications in the document ISR 2020-08, and the recomendation by the CS.
We therefore leave the Phase II unchanged with the reported warnings.
[2021-12] We run the orbit and visit planner. When running the visit planner, we got first the error "Fatal Error encountered when computing schedulability".
A second time we got the error "Internal CASM error: no methods applicable for generic function #<STANDARD-GENERIC-FUNCTION-ORBITPCS-TASK> with args(NIL) of classes (NULL).
Please contact your PC". In accordance with assistant scientist, we submit the apt anyway to show the error.The Environment of the most distant Radio Loud QuasarHigh-redshift luminous QSOs (z~6) already host billion solar masses black holes in their centers, and are
predicted to live in high-density peaks of the dark matter distribution, surrounded by overdensities of galaxies.
Previous searches for Lyman Alpha Emitters (LAEs) with narrow-band (NB) imaging around radio-quiet high-z
QSOs did not recover such overdensities. These QSOs redshifts were determined only via broad, high-
ionization emission lines in the rest-frame UV, often strongly shifted with respect to the systemic redshifts.
Alternatively, radio-loud sources have been commonly found in rich environments, pinpointing the first
protoclusters in the universe.
Here, we propose HST imaging observations to search for LAEs in the field of PSO172+18, the most distant
radio source and the radio loudest QSO at z>6, using a suite of narrow and broad band filters with WFC3 and
ACS/WFC. The systemic redshift of PSO172+18, z=6.823+-0.002, is accurately measured from
observations of the narrow MgII emission line, and precisely locate the Lyman Alpha emission line in the
response of the narrow band filter F953N, uniquely available on board HST.
Additionally, we will detect (or derive tight constraints on) the stellar emission of the QSO host galaxy, and
search for any potential close (-kpc scale) companion.We will use four filters, i775 (F775W) and z850 (F850LP) with the ACS/WFC instrument, J (F125W) with the WFC3/IR camera, and the narrow band F953N with WFC3/UVIS.
We calculate the exposure time using the WFC3/UVIS, WFC3/IR andACS/WFC online Exposure Time Calculators.
We will be able to reach our science goals with observations of ~29000s in the F953N filter, with a 3sigma limit magnitude of 25.4 (AB mag). This is accomplished in 15 orbits.
On the other hand, we aim to achieve a depth of z850=26.6AB mag at S/N~5. This is achievable in 3 orbits.
Additionally, we plan to reach a depth i775= 27.6 AB mag. We can do this, at S/N~5, requiring 4 orbits.
Finally, we ask for 3 orbits for J (F125W) observations at a depth comparable to i775 (F125W=27.5 AB mag).
We will perform dithering observations in order to cover the regions between the fields of view of WFC3/IR and WFC3/UVIS, using the dithering pattern WFC3-IR-DITHER-BOX-UVIS for WFC3/IR. In order to better sample the PSF in the IR, we also implement a sub-pattern WFC3-IR-DITHER-LINE-3PT for WFC3/IR
Dithering will also allow us to cover the gap between the two WFC CCDs, and to better treat bad pixels and cosmic rays.
Since we need to cover the same region with all the observations and all the filters with WFC3 and with ACS separately, we restrict the visits with the same cameras to have the same orientation.
On the other hand, given the comparable fields of view, leaving free the relative orientation of WFC3 and ACS will only lead to a loss of a maximum of <10% of field of view coverage (in the worst case scenario of a 45deg orientation).
This change with respect to Phase 1 was approved by the Telescope Time Review Board following the Change Request 91796 on July 7th 2020.
In practice, we achieve our goal for ACS by constraining visits (02) and (03) to have the SAME ORIENT as PSO172_ACS_z1_1 (01); for WFC3/UVIS and WFC3/IR by requiring visits (05) - (09) to have the SAME ORIENT as PSO172_WFC3IR_J (04).
As suggested by the Instrument Handbook and by recent documentations (ISR 2020-08), we aim to reach a background level of ~20e- in each WFC3/UVIS F953N observations (to better deal with CTE issues).
In order to do this, we opt for one exposure per orbit (texp = 2765s), which produces ~7.8e- of natural background (as per ETC calculations). In order to reach the recommended background level of ~20e-, we also add POSTFLASH=15,
[2021-12]: Following problems with scheduling the WFC3 observations due to lack of guiding stars, we have created new visits to replace old visits (4) - (9). We created visits (10) - (24) with WFC3-UVIS F953N filter with only one orbit per visit. We used a WFC3-UVIS-DITHER-LINE pattern, with two exposures per orbit (i.e. per visit). In order to reach a background level of ~20e- in each F953N observations, we add POSTFLASH=17. The natural background with new texp=1313 is indeed ~4.1e- (see linked ETC calculation). To ensure the same orientation as the observations in WFC3-IR, we linked each visit (10) - (24) to have the SAME ORIENT as visit (25).
We distribute the observations with WFC3-IR in 3 visits (one orbit per visit), (25) - (27). We link all visits to have the SAME ORIENT as visit (25). We use the new pattern WFC3-IR-DITHER-BOX-UVIS, with no sub-pattern.
[2021-12-21]: Following further suggestions by support, we made the following changes. We added WFC3-IR-DITHER-LINE-3PT dither pattern to the IR observations on top of the already used WFC3-IR-DITHER-BOX-UVIS pattern. This was done using the POS-TARG values for the WFC3-IR-DITHER-LINE-3PT pattern (with POS-TARG=(0.00,0.00),(0.451, 0.403),(0.902, 0.806)) on each orbit/visit such that each IR orbit/visit executes at one of the locations of the WFC3-IR-DITHER-LINE-3PT pattern. Each IR orbit/visit continues to use the WFC3-IR-DITHER-BOX-UVIS pattern.
We added WFC3-UVIS-DITHER-LINE-3PT dither pattern to the UVIS observations on top of the already used WFC3-UVIS-DITHER-LINE pattern. This was done using the POS-TARG values for the WFC3-UVIS-DITHER-LINE-3PT pattern ((0.00,0.00), (0.092, 0.098), (0.185, 0.197)) on each orbit/visit such that each UVIS orbit/visit executes at one of the locations of the WFC3-UVIS-DITHER-LINE-3PT pattern. Each UVIS orbit/visit continues to use the WFC3-UVIS-DITHER-LINE pattern. We slightly increase the exposure time of F953N from 1313s to 1398s, to reduce the unused orbit time. In order to reach a background level of ~20e- in each F953N observations, we add POSTFLASH=17. The natural background with new texp=1359 is indeed ~4.3e- (see linked ETC calculation).The team is composed by experts in observations and studies of galaxies and QSOs in the epoch of reionization, with a solid experience in treating HST data.

Added WFC3-UVIS-DITHER-LINE-3PT dither pattern to the UVIS observations on top of the already used WFC3-UVIS-DITHER-LINE pattern. This was done using the POS-TARG values for the WFC3-UVIS-DITHER-LINE-3PT pattern (given in Table C.3 of WFC3 IHB; https://hst-docs.stsci.edu/wfc3ihb/appendix-c-dithering-and-mosaicking/c-2-wfc3-patterns) on each orbit/visit such that each UVIS orbit/visit executes at one of the locations of the WFC3-UVIS-DITHER-LINE-3PT pattern. Each UVIS orbit/visit continues to use the WFC3-UVIS-DITHER-LINE pattern. This reduces the repetitions in UV pointings from 15 times down to 5 times.
