This plot

This is the trending report for UVES QC parameters derived from the Cross-Disperser Alignment reproducibility frames.

These data are taken daily. Each Cross-Disperser [CD] is moved into position such that the zeroth order from the echelle falls on the detector and the first frame is exposed, then the CD is moved away, and then moved back into position and the second frame is taken. Ideally, if the mechanical mechanisms are working perfectly, the zeroth order will appear at exactly the same position in the two frames. So this data tests the reproducability of the instrumental setup, in particular that the instrumental setups used during the night can be accurately reproduced during daytime calibrations.

The spatial position of the zeroth order is then measured at a number (~25) positions along the order in the two frames. Plots 1 to 4 display the mean of the differences between the measured positions in the two frames.

Find more information about UVES CD_ALIGN frames here.  


General information

Click on any of the plots to see a close-up version.

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
