The reference pixels of MIDI are the two pixels of the detector onto
which the centroids of the target images must fall in order to ensure a
proper beam overlap. They are measured using the center of a pinhole,
in the 3 set-ups OPEN, HIGH_SENS and SCI_PHOT, for telescopes beams A
and B feeding MIDI, for the interferometric channnels 1 and 2 of MIDI,
and for the photometric channels PA and PB of MIDI (in SCI_PHOT only).
General information
Click on any of the plots to see a close-up version.
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
