It appears the program did not have co-Is listed, so I have added them (O'Connor, Baggett, Mack). 2. 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. 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, and G-type star P330E 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, especially in RGM. Overview ------- This Cycle 33 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: six visits for the white dwarf GRW70, four visits for the white dwarf GD153, and two visits for the solar-type star P330E. Changes ------- The Cycle 32 monitoring program (17682) was designed such that P330E was allocated three orbits, GRW70 five orbits, and two orbits each for GD153 and the A-type star TYC 4212-455-1. TYC 4212-455-1 was only scanned in Cycles 31 and 32; the observed data is a valuable resource to test the methodology of absolute photometry of spatial scans (see Analysis section below), but the target is not as useful for continued monitoring of temporal changes to detector sensitivity due to the shorter baseline of observation compared to the other targets. Therefore, with this Cycle 33 calibration program, we discontinue observing TYC 4212-455-1. We redistribute the two orbits that TYC 4212-455-1 was alloted in Cycle 32 to the white dwarf standard GD153. Additionally, we reduce the number of P330E visits of P330E from three to two, and allocate that orbit to GRW70 instead. Target Scheduling -------------- GD153 scan photometry has reduced scatter relative to that of GRW70 (WFC3 ISR 2022-04, Marinelli et al.) but the visibility of GD153 was significantly limited immediately after the onset of RGM operations, which is why GD153 was only observed twice in Cycle 32. To maximize the scientific utility of this calibration program, it is imperative to optimize the available window of schedulability during this cycle. Therefore, we intend to observe GD153 four times during Cycle 33. For GRW70, we increase the number of visits from five to six, which is the same allocation as Cycle 31. In comparison to GD153, 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 the final two visits (09 and 10) both span about three 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 33, two orbits are dedicated to this target. Visits are executed at least 3 months apart to ensure good temporal sampling within 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 are taken with increasingly red filters until reaching F814W, at which point we switch to UVIS 1 and scan in increasingly blue filters. Each visit draws from a "core" set of commonly-used wide-band filters: F218W, F225W, F275W, F336W, F438W, F606W, and F814W. In each visit of the white dwarf standards GD153 and GRW70, we also perform scans using less commonly used wide-band filters (F390W, F475W, F555W, F625W, and F775W) on one of the two subarrays. This helps ensure the auxillary filter coverage is as even as possible between UVIS 1 and UVIS 2. In most cases, scans use the same parameters: 60s exposure time, 7.5'' scan at 0.125''/s. However, P330E scans in the bluest filters (F225W and F275W), 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 requires longer, slower scans in the bluest filters, it has fewer scans than the white dwarf standards. 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 enables standard photometric/sky aperture sizes as well as custom apertures for optimizing analysis of scans of different lengths (i.e. the UV scans of P330E and Cycle 31/32 target TYC-4212-455-1). Results from this work, as well as updated relative photometry, will be published in Marinelli & O'Connor 2025 (in prep). 0 false false false RESTRICTED CALIBRATION PHOTOMETRIC NO Coordinates copied from LAWD-52 generated from SIMBAD database with proper motion applied to give coordinates with epoch of 2000 (proper motion corrects to 2025).
