MTA Monitoring Report 08/05/05 - 08/11/05

Archive of monthly reports

Note - The very high peak seen on a focal plane temperature plot and the high temperatures of the cold radiator on DOY 220 were due to ACIS focal plane testing.

Extended high focal plane temperature shoulders are seen on perigee egress for the last two orbits, DOY 218 and 221-222.

Detrended CTI

CTI page was updated. The top panel shows an example of detrended CTI measurements from the front illuminated CCD3 Node 0. The top plot is all data points without any temperature dependency correction. The middle plot is data with the focal temperature equal or colder than -119.7 C, and the integration time longer than 7,000 sec. The bottom plot is all data with the temperature correction.

The values quoted below are temperature factor corrected ones.
Average of ACIS-I CCDs (MnKa) slope 4.433e-9 CTI/day
Detrended slope 7.736e-9 CTI/day

ACIS Focal Plane Temperature

For this period, 4 peaks are observed.

Day (DOY)	Temp (C)	Width (Days)
217.72	-89.59	0.34	a peak due to the focal plane temperature test
218.26	-114.86	0.79	right shoulder
220.00	-115.19	1.58	very long but low right tail
223.80	-118.09	0.46


Weekly focal plane temperature with sun angle, earth angle, and altitude overplotted. Sun angle is the solar array angle, that is the angle between the sun and the optical axis (x-axis). The earth angle is the angle between earth and the ACIS radiator. This calculation is under review and currently may superimpose +Z and -Z angles. Altitude varies from 29 kkm to 120 kkm.
