Description

Looking at HgCd arcs we are missing quite a few lines in the HgCd.txt file (see ); please add them (e.g. from NIST)

I checked, and I don't think that the lines are from the Ar carrier, but I could be wrong. There are some weak lines which extend the blue coverage, but it isn't clear how useful they are.

The values from Hg.txt should be vacuum wavelengths.

Output from running reduceExposure.py with new line lists vs old, with 38080 line centroids vs 5950. All other processing parameters were the same.

We have dropped the one HgII line from the new list at 734.85320 228.57 HgII 0. I'm assuming this was intentional? Christian Kragh Jespersen

Should be, if I remember correctly there's another line close by, it's a blend with intermediate distance, so we can't really merge them nor separate them since we didn't have any info on the intensity of the other line.

Checking on a single, visit (v106863, same as above), we see more lines detected but get some larger median and soften values, mostly for the wavelength in the the n and r arms. For n we simply weren't detecting any lines to have valid wavelengths (which is the issue that started us looking into this in the first place).

Rebuilding the detectorMaps with these line lists should improve this so after merging this file I think the detectorMaps should be updated.
