QC1 plotter - general comment: Increase of the RON is often due to power cuts and/or high pressure (see pressure 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).
