Wavelength calibration: trending of cross correlation results.

The cross correlation result is a unitless number between 0 and 1. Values above 0.2 are regarded as acceptable. For lower values, the CRIRES pipeline disregards the result and returns -1. Such values are marked as "aliens" (red arrows) in the plots.

The cross correlation results are monitored for the two daily health check settings with reference wavelength (on chip 3) of 1090.4nm using ThAr lamp and 4092.9nm using N2O absorption cell.

Chips 1 and 4 of the 1090.4 nm setting suffer from vignetting. Pipeline results are arbitrary and are not plotted.

Pipeline processing in Garching applies dark subtraction and flat-fielding. This can result in better cross-correlation values, especially for chip 2 (1090.4 nm) and chip 4 (4092.9 nm) where Paranal results are not displayed.
