12735( 2) - 05-Oct-2011 20:19:01 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 12735 Version: 2 Check-in Time: 05-Oct-2011 20:19:01 STScI Edit Number: 0 Title ACS Internal Flat Fields ------------------------------------------------------------------------------------ Type Cycle CAL/ACS 19 ------------------------------------------------------------------------------------ Investigators Contact? PI: Matt Mcmaster Space Telescope Science Institute CoI: Dr. Ralph C. Bohlin Space Telescope Science Institute N ------------------------------------------------------------------------------------ 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 and to monitor the position of the dust motes. ------------------------------------------------------------------------------------ Observations Description ------------------------ Internal flats will be obtained for the WFC detectors using the tungsten lamps. 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 2-3 months before the end of the cycle. Real Time Justification ----------------------- 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% Additional Comments ------------------- ------------------------------------------------------------------------------------ 12735( 2) -
