Hot Pixels
Mainly Column 64 Hot Pixels

Noisy Pixels
Decrease in number of Noisy Pixels due tomodified blanking of Column 64 segments in latest BPT update (Rev 1408 onwards)

Offset Median
Increase in offset median: 2 – 5 ADU for Q0 CCDs since ~ Rev 1410
Perhaps other CCDs also, e.g. CCD5
Coincides with latest PN BPT implementation (Rev 1409); however, the changes in the BPT affected CCD11 only…
Similar to onset of theoffset median trend seen in Revs 605 – 660

Offset Median (cont.)
Regarding the Rev 605 – 680 offset median trend:
A correlation was found with the respective Quadrant VC Currents (params F1189-92)
(discussed at the Saclay 2003 Ops Meeting)…

Offset Median (cont.)
F1189: Q0 VC Current
…however, in the recent trend:
NO correlation with VC Current found.

Energy Scale vs Time very good, esp. for FF mode.
Slight over-correction for EFF mode.
SW mode under-correction, esp. at Mn

Still fewer Bad Pixels than before cooling
Nevertheless, steadily increasing trend for most CCDs

New MOS fixed offsets from Rev. 1400 onwards.
MOS fixed offsets lowered by 1 ADU for:
- MOS1 CCD 5
- MOS2 CCDs 1, 2, 3 and 6
