A new telemetered photon dose map trend

To monitor accumulative exposure effects on ACIS, we created cumulative exposure map once a month from all observations, including calibrations, using evt1 data of that month. This map is added on all previous exposure maps, and then statistics of the total exposure map is computed.

You can find this at Telemetered Photon Dose Map

A Step by Step Example of Correcting Temperature Dependence of CTI

To show how we correct temperature dependence of CTI, we added a step by step example of the correction. Please see: CTI correction page

Radiation

Quiet.

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 4.993e-9 CTI/day
Detrended slope 6.377e-9 CTI/day

ACIS Warm Pixels

We display all bad pixels showed up in past, and, if any, previously unknown bad pixels appeared in the last 14 days. We also list hot pixels (defined as 1000 above the average of bias background). Warm columns 509-514 are probably due to a computational artificial effect due to boundaries.

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