CCD Temperature Monitoring

These four figures track the CCD temperature and TEC status of each XIS. The three panels in each figure show, as a function of time, the CCD temperature (top), the baseplate temperature (middle), and the TEC voltage (bottom). The vertical lines near 12 August 2005 indicate the opening of the XIS doors. Carets indicate data points that fall out of the vertical range of the plot.

Also available for each CCD is a list of anomalous temperature excursions accumulated over the life of the mission. These are summarized here.

The fifth figure shows the temporally-smoothed baseplate temperatures for all four detectors.
