This plot

The readout noise of MIDI is monitored by taking a full-frame exposure with a large number of frames, with the MIDI shutter closed and with a minimum DIT. The standard deviation of the pixel level over the frames is computed by the pipeline for each pixel, as well as the median of the standard deviation over all the pixels and all the frames, which is plotted here (expressed in detector ADUs).  


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
