17339( 2) - 17-Jun-2024 12:32:56 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 17339 Version: 2 Check-in Time: 17-Jun-2024 12:32:56 STScI Edit Number: 0 Title ACS Internal Flat Fields ------------------------------------------------------------------------------------ Type Cycle CAL/ACS 31 ------------------------------------------------------------------------------------ Investigators Contact? PI: Yotam Cohen Space Telescope Science Institute Y ------------------------------------------------------------------------------------ Abstract The stability of the CCD flat fields will be monitored using the calibration lamps. One set of observations for all the filters and another at a different epoch for a subset of filters will be taken during this cycle. High signal observations will be used to assess the stability of the pixel-to-pixel flat field structure, to analyze image artifacts such as the newly discovered flecks, and to monitor the position of the dust motes. ------------------------------------------------------------------------------------ Observations Description ------------------------ Internal flats will be obtained for the WFC detector using the tungsten lamp. One set of internal flats will be obtained for the entire filter set about 2-3 months into the cycle. Another set will be obtained using a subset of filters (F435W, F625W, F814W, and F850LP) about 6 months after the first set. High signal observations will be used to assess the stability of the pixel-to-pixel flat field structure, to analyze image artifacts such as the newly discovered flecks, and to monitor the presence of dust motes. Any changes in time of P-flats will also be tracked. Note: Due to increases in exposure time to account for lamp dimming, orbits have now exceeded the 1800 second recommended maximum. To mitigate this overrun, last cycle, we changed the program design such that we shifted singletons of the longer exposures into adjacent filters' orbits and vice-versa. ------ Calibration Justification ------- Results from this program will impact the standard flat field calibration files included in the pipeline. The accuracy of the flat field calibration is expected to be better than 1% for WFC broadband filters. ------------------------------------------------------------------------------------ 17339( 2) -
