EPIC MOS Monitoring

Detailed report by Martin Stuhlinger on monitoring the bad pixel situation and charge transfer inefficiency (CTI) stability in ESA spacecraft, along with suggested adjustments for long-term drift compensation. Current CTI model remains valid.

  8. Conclusions Bad pixel situation is still stable on low level. • Possible adjustment of background: decrease fixed-offset table of several CCDs by 1 ADU to compensate long-term drift. • Serial CTI stable since cooling except MOS2 CCD7. • Parallel CTI stable since cooling. Science ~rev. 700 parallel CTI nearly constant. • Current CTI model still valid. Martin Stuhlinger, ESAC
