This plot

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
