Memory Management
Spacecraft Status
The ADP hung on Sunday (Feb. 10), requiring a reset of the ADP on Monday the 11th.
Data Gaps
No gaps in monitor rates.
Detector issues
A week ago we increased the rear fast threshold on detector 4 to cut down excessive rates that were degrading livetime for that detector segment by about 10%. The threshold change was immediately effective in reducing the excessive counts and the livetime is no longer compromised.
Detector 2 remains unsegmented, with no hint of segmenting soon. The current plan is to remain at this voltage for awhile to get a sense of how spectral parameter changes are related to radiation damage (as opposed to HV changes).
