CTI Trend

Average of ACIS-I CCDs (MnKa) slope 2.223e-8 CTI/day
Detrended slope 1.474e-8 CTI/day

It is clearly seen that CCD 4, 8, and 9 had a wide peak between DOM 400 and 500. It seems that the trend is back to the original track.

ACIS Focal Temperature

For this period, there is only one peak.
       Day (DOY)       Temp (C)        Width (DAY)
       339.5           -116.2          0.27

MTA Problem Tracking

All problems reported before Dec 31, 1999 are closed on Dec 6, 2000. However, the following two problems are immdiately reopened:

AOVAMPWR, AOFUNLST 1DPDBBON,ASPEB5CV, AGWS2V

We are planning to close the permanantly this week.

Recent Observations

The ACA Problem is in the specified handling of guide star positional errors. This issue in not signifcant to the final product and so is being worked at low priority.
