1 XMM 1Michael Smith, ESAC EPIC PN Monitoring Provided by Michael Smith

2 XMM-Newton 2 Michael Smith, ESAC PN Bad Pixel & Offset Monitoring Since last meeting: FF offset map calculation using 50 frames (as opposed to 100) since ~ rev 842. Additional bad pixel (type ‘H’, i.e. not up-linked) included in EPN_BADPIX CCFs: CCD 1, (RAWX,RAWY) = (56,75)

3 XMM-Newton 3 Michael Smith, ESAC Hot Pixels (E > 744 ADU in Offset Map)

4 XMM-Newton 4 Michael Smith, ESAC Offset Map Mean

5 XMM-Newton 5 Michael Smith, ESAC Offset Map Variance

6 XMM-Newton 6 Michael Smith, ESAC Noisy Pixels (> 1% Occurrence in CalClosed)

7 XMM-Newton 7 Michael Smith, ESAC Energy monitoring over-correction with time tailed out with new CTI CCF (13) for all modes eFF mode over-correction improved (see talk M.Pilar Esquej) Still not understood problem of SW mode (CC data not applicable for SW, however in first approximation a over correction would be expected: we see an under-correction ???

8 XMM-Newton 8 Michael Smith, ESAC Conclusions Hot pixel situation is stable. Offset Map mean is stable again after small excursions around rev 600 (mentioned in previous Ops meetings). Offset Map variance for FF mode has changed after ~ rev 842; probably related to the introduction of 50 frame offset calculation. The change is more pronounced in some CCDs (e.g. Quadrant 1 and CCD11) than in others. Noisy pixel situation is stable. Current Bad Pixel Table still valid.
