Continued from last week:
Accumulated fluence for orbit 290 (DOM 784) was 3.09e+09 p/cm^2-sr-MeV.
This week:
Relatively quiet. Moderate solar activity bears watching.
Increased background rates continue near rad zone entry. The plot below
covers the period since Sept. 01, 2001 and is smoothed on a 5 min.
interval without distinguishing any grades/quality of data. Obsids affected
this week:
1041,
1613. OBSID 1022 (DOM 784), which
shows S2 high, is a grating observation of a bright source, so this is
not data on the radiiation situation.
Average of ACIS-I CCDs (MnKa) slope 1.419e-8 CTI/day
Detrended slope 1.324e-8 CTI/day
