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).
