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

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
