Instrument Science Report 2001-09:The WFPC2 Photometric CTE MonitorI. Heyer October 05, 2001 Abstract: The Charge Transfer Efficiency of the WFPC2 CCD arrays has been monitored since the instrument's deployment aboard HST in 1993. Since then a significant increase in CTE loss has been observed. We examine photometric data from 28 April 1994 to 11 February 2001. The CTE loss appears to be growing worse in a linear fashion with time. The results from the latest set of observations show that CTE loss has reached a level of 53% in the worst case scenario.
