This plot

This plot shows the resolving power.

The spectral resolution (resolving power) R = Lambda / DeltaLambda as calculated by the pipeline and stored in the QC1 DB is given 'per sigma'. These values are divided by 2.3548 ( = FWHM / sigma = 2 sqrt( 2 ln(2) ) ) for the plot to be expressed in 'per FWHM'  

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
