This plot

Trending plot for wavelength calibration.

The positions of two reference wavelengths (2.099 and 2.314 microns) on the detectors are trended for the lowest spectrum on the detector. Scoring thresholds have been set up provisionally to +/-2 pixels around the median (for SC high resolution) and +/-1 pixel for SC low and medium resolution.  

General information

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

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • 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
