E.4 The Cycle 18 Calibration Plan
The Cycle 18 calibration plan is summarized in WFC3 ISR 2011-14. It was executed from October 2010 through September 2011. The calibration programs comprising this plan are listed in Table E.5. The proposals and observation dates can be viewed by entering the Proposal ID into the HST Program Information webpage. The Cycle 18 plan provides less frequent monitoring of characteristics that were demonstrated to be stable during Cycle 17. It places increased emphasis on characterizing IR persistence, measuring UVIS and IR flat fields, calibrating the IR grism, monitoring CTE on the UVIS detector, and quantifying the ability to do high contrast imaging on both detectors. It tests CTE mitigation procedures and the performance of spatial scans for high S/N IR observations.
The results of these calibration programs have been documented in Instrument Science Reports on the WFC3 website at:
