... The WF/PC-1 camera heads were decontaminated on February 3, 1992 (day 034), following a long period of continuous cold operation of the WF/PC-1 CCD detectors during which many science observations were obtained. ... However, unlike previous decontaminations, the February 3,1992 procedure caused the re-appearance of the measles contaminant. ... Figure 46.2 shows a 100 x 100 region of the PC6 and PC8 detectors (divided by a flat taken before the measles problem appeared) at 4 epochs. ...
