This plot

This is a trending plot monitoring temperatures of the VISIR imaging and spectroscopic detectors. As of May 12, 2010 the temperature of the imaging detector is read from keyword INS_TEMP30_VAL and of the spectroscopic detector from keyword INS_TEMP31_VAL. Before that date different keywords were used - INS_SENS30_VAL and INS_SENS31_VAL respectively.  


General information

Click on any of the plots to see a close-up version.

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • statistical averages are indicated by a solid line, and thresholds by broken lines
  • outliers are marked by a red asterisk. They are defined as data points outside the threshold lines
  • "aliens" (= data points outside the plot Y limits) are marked by a red arrow ( or )
  • you can download the data for each parameter set if the 'Data downloads' link shows up
