ACS 9658

ACS Earth Flats

This program will obtain sequences of flat field images by observing 
the bright Earth. Several UV filters from the interim calibration 
program {9564} require additional exposures to obtain the required 
illumination. A few UV filters from this program will be repeated to 
monitor for changes in the flat fields and to verify the interim 
results. Since no streaks are observed in the UV, the wavelength 
coverage is extended to longer wavelengths in order to explore the 
severity of streaks in the flats from clouds in the FOV. We have added 
exposures for the HRC in the visible filters to verify the results 
derived from the L-flat campaign and to explore the severity of 
streaks. We have also added exposures on WFC using the minimum 
exposure time and using filters which will not saturate the brightest 
WFC pixel by more than 10 times the full well.
