Updated Visit 07 requirements to execute at least 2 days after Visit 06. 2025-04-16: Updated window for Visit 05 to correct BETWEEN error that prevented scheduling. 2025-04-24: Added Visit 51 to replace Visit 11, which suffered a guidestar failure resulting in unusable data. Additional orbit is authorized by HOPR 93176, filed on April 2nd, 2025 and approved April 7th, 2025. 2025-04-28: Updated Visit 05 BETWEEN to span end of June through early July. While the BETWEEN for Visit 08 (also GRW70) includes this visibility window, the posted scheduling window currently is Aug 16-23rd, so I did not add any AFTER conditions to reinforce visit spacing. 2026-01-26: Updated BETWEEN for orphaned Visits 05 and 51 in order to schedule for early 2026. -360623391 ----- Attempting Submission 1 (Tue Nov 19 23:02:26 GMT 2024) ----- Your proposal could not be saved.

The merging rule violations are because of shifting from UVIS 2 to UVIS 1 without GS reaquisition, which has historically been allowed due to the nature and goal of these observations. 3. I am not sure why we continue to get the warning "Exposure duration 59.9 was not an integer multiple of .1 seconds. It has been adjusted to 59.900000000000006", but we have previously been assured that it's is okay. 2024-12-18 changes: - Moved window for Visit 02 to earlier in the year due to limited guidestar availability. - Updated window for Visit 06 to a couple months later due to limited guidestar availability, overlapping the window for Visit 07. - Updated Visit 07 requirements to execute at least 2 days after Visit 06. 2025-04-16 changes: - Updated window for Visit 05 to correct BETWEEN error that prevented scheduling. 2025-04-24 changes: - Added Visit 51 to replace failed Visit 11, authorized by HOPR 93176 (approved April 7th, 2025). 2025-04-28 changes: - Updated Visit05 window to cover June 26th-July 7th, since the previous update came through too late to schedule it in May. 2026-01-26 changes: - Updated Visit05 and Visit51 windows so they can be executed in early 2026. Adjusted filters for Visit05 after reviewing filter coverage stats. WFC3 UVIS Time Dependent Sensitivity This program acquires scanned observations for monitoring the relative changes in the WFC3/UVIS photometric throughput. The spectrophotometric white dwarf standard stars GD153 and GRW70, G-type star P330E, and A-type star TYC-4212-455-1 are scanned in a subset of filters periodically over the year. Historically, this program was intended as a monitor of the UV filters as they provide a means to detect contaminants on the instrument optics, with one or two visible/red filters serving as a control. Since then, additional filters in the visible and red have been added to the program to expand the monitor to longer wavelengths. The observing cadence is roughly once a month though some exceptions are required to accommodate visibilities. Overview ------- This Cycle 32 monitoring program uses the spatial scanning observing mode to monitor the photometric stability of the WFC3/UVIS channel. Each visit of the 12 in this program spends one orbit on a single standard star: five visits for the white dwarf GRW70, two visits for the white dwarf GD153, three visits for the solar-type star P330E, and two visits of the A-type star TYC-4212-455-1. Changes ------- The Cycle 31 monitoring program (17362) was designed such that GD153 and P330E were allocated three orbits each, while the remaining six orbits were allocated for GRW70. However, due to guidestar failures and the impact of reduced gyro mode (RGM) on schedulability, two P330E visits were re-allocated: one was reassigned to GD153, and the other was converted to observe TYC-4212-455-1, the first A-type star added to the UVIS scan monitor. Therefore, with this Cycle 32 calibration program, we continue observing these four targets. Target Scheduling -------------- As previously reported (WFC3 ISR 2022-04, Marinelli et al.), GD153 scan photometry has reduced scatter relative to GRW70. On this basis, combined with the reality that schedulability of GD153 is constrained within approximately two consecutive months due to RGM, we decided to only observe GD153 twice, with a separation of at least five days between the two visits. For GRW70, we return to five orbits, which is the same allocation from the Cycle 25 program (15398) to the Cycle 30 program (17016). Since GRW70 is visible more often throughout the year in RGM, we space the visit windows to at least three weeks apart, guaranteeing at least one visit in the first, second, and final quarters. The windows for two visits (07 and 08) span about two months in order to capture two smaller windows of target visibility each. P330E was first added to the UVIS scan monitor in 2020 (Cycle 27, program 16021); in Cycle 32, three orbits are dedicated to this target. Due to visibility restrictions, the visits are placed in the first, second, and third quarters of the cycle, a minor departure from previous cycles wherein we attempted to observe P330E in the first, third, and last quarters of the cycle. We will observe TYC-4212-455-1 twice: once in the second quarter of the cycle, and once in the last quarter of the cycle. Visit Parameters ------------- In each visit, scans alternate between "reverse" and "forward" direction to maximize "time-on-target". Scans begin on UVIS 2 with either F218W (both white dwarfs) or F225W (P330E and TYC-4212-455-1), and are taken with increasingly red filters until reaching F814W, at which point we switch to UVIS 1 and scan in increasingly blue filters. Since UVIS 2 has greater sensitivity than UVIS 1, we choose to execute about twice as many scans on UVIS 2 than UVIS 1 for all targets except for P330E. In most cases, scans use the same parameters: 60s exposure time, 7.5'' scan at 0.125''/s. However, P330E and TYC-4212-455-1 scans in the bluest filters (F225W and F275W, plus F336W for TYC-4212-455-1), require several hundred seconds at 0.01''/s for scans of 3-5" in length. Consequently, the total number of scans per visit differs by target; since P330E and TYC-4212-455-1 require longer, slower scans in the bluer filters, they have fewer scans (11 and 9, respectively). Analysis ------- Scan photometry is vital to the continuing photometric calibration of the WFC3/UVIS channel. Previous results have been reported in WFC3 ISR 2023-02 (Marinelli & Bajaj), WFC3 ISR 2022-04 (Marinelli et al.), WFC3 ISR 2022-02 (Medina et al.), doi 10.3847/1538-3881/ac73f0 (Calamida et al. 2022), WFC3 ISR 2021-04 (Calamida et al. 2021), WFC3 ISR 2017-21 (Shanahan et al.), WFC3 ISR 2017-15 (Shanahan et al.), and WFC3 ISR 2017-06 (McCullough). An actively-maintained, automated monitoring pipeline (internal-only) exists to download new visits, perform data reduction, and aggregate the resulting relative photometry into catalogs and plots. The pipeline currently uses standard photometric/sky aperture sizes for all targets/filters; work is ongoing to optimize the apertures for scans of different lengths (i.e. the UV scans of P330E and TYC-4212-455-1). Results from this work, as well as updated relative photometry, will be published in a future ISR. 0 false false RESTRICTED CALIBRATION PHOTOMETRIC Coordinates copied from LAWD-52 generated from SIMBAD database with proper motion applied to give coordinates with epoch of 2000 (proper motion corrects to 2024).
