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)…

…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
