WFPC2 Technical Instrument Report 08-01:

PSF Characterization for the HST One-Gyro Mode Test

-M. Sirianni and M. McMaster

We have analyzed the WFPC2 data taken during the on-orbit one gyro test which occurred January 29-31, 2008. This program was designed to investigate whether one-gyro guiding would degrade WFPC2 image quality. Science data obtained in one-gyro mode are essentially indistinguishable from those obtained in two-gyro mode.
