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).

If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
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
