Operations CXO Status Report

Friday 14 April 2017 9.00am EDT

During the last week Chandra completed the observing schedule as planned.

A real-time procedure was executed on Apr 11 to uplink a flight software patch that updates the Calibration of Fine Sun Sensor B. Additional real-time procedures were executed on April 12 and 13 to dump OBC-A and -B memory as a follow-up to the patch. The dump will be used to update the baseline memory images maintained on the ground.

Of note this week was the release on Apr 13 of Version 4.9.2 of the Contributed Scripts package for CIAO. The release includes several updates including chandra_repro, simulate_psf, and specextract Further details on the changes may be found at: ,a href="http://cxc.harvard.edu/ciao4.9/download/scripts/history.html" target="_blank">http://cxc.harvard.edu/ciao4.9/download/scripts/history.html
