At the 259:0345 pass the OC/CC noticed that the DEA-A was off. A quick analysis shows that the DEA-A voltages and currents were nominal up until the major frame at which the DEA shut off. The ACIS team assessment is that this looks like the two cases where DPA turned off. Those were not assigned a definitive cause, but the best hypothesis was a cosmic ray hit to the opto-isolator causing the PSMC to send a spurious command to turn off.

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 4.378e-9 CTI/day
Detrended slope 7.696e-9 CTI/day
