The Cycle 17 calibration plan was executed from September 2009 to October 2010. The calibration programs comprising this plan are listed in Table E.4
. The proposals and observation dates can be viewed by entering the Proposal ID into the HST Program Information Web page
. The initial plan provided improved photometric, spectroscopic, flat field, and geometric distortion values and additional on-orbit detector characterization. Supplemental programs, beginning with proposal ID 12087, were introduced mid-cycle to provide data needed to improve calibration in specific areas and to characterize problems or anomalies.
The overall Cycle 17 calibration plan is discussed in WFC3 ISR 2009-08
, with more details available concerning the photometric calibration of WFC3 (WFC3 ISR 2009-05
) and the detector monitoring campaign (WFC3 ISR 2009-07
). Galactic cluster observations are a cornerstone of the Cycle 17 calibration effort (WFC3 ISR 2009-06
