Results of the WFPC2 Post-Srevicing Mission-2 Calibration Program

January 14, 1998
WFPC2 underwent an extensive series of tests and calibrations following the 1997 HST servicing mission. Herein we summarize the results of these tests. The servicing mission appears to have caused essentially no change in the performance and calibration of WFPC2. The photometric calibration, baseline far-UV response, focus, PSF, flat field, read noise, A-to-D gain, dark current, and optical alignment all appear identical to those before the servicing mission. The only discernable effect of the servicing mission was a small and temporary increase in the rate at which contaminants collected on the cold CCD windows. This will have a small effect on UV data taken in March and April 1997; these observations will require non-standard contamination corrections which are discussed herein.
