Detrended CTI

CTI analysis is now computed with "detrending":
Detrend CTI = Measured CTI + S3 amplitude reject rate * Detrend factor.

Average of ACIS-I CCDs (MnKa) slope 9.070e-9 CTI/day
Detrended slope 9.220e-9 CTI/day

Recent Observations

"Prob" means that there was probably bad time data included in the manual runs. This will be corrected in future processing.

Trending

This Week's focus HRMA THERMAL GRADIENTS.


These are ground comps of adjacent HRMA thermistors. Most are very stable. Gradients with particularly secular changes include:
RT25-RT26: and all other HRMA STRUT pairs,
RT48-RT53: OBA Cone Panel,
RT52-RT53: OBA Cone Panel,
RT34-RT35: OBA Cone Panel (seasonal and secular effects),
RT78-RT79: Spacecraft Struts,
RT61-RT62: TFTE Cone (TFTE has many strong gradients)

Trends last reported on Oct 24.
