    initial v1  
    11'''Wavelength Scale'''

    3 I've updated the spectral lines file (new_spectral_lines_feb16.csv) to identify most of the spectral lines, from the Oriel booklets we have and http://www.nist.gov/pml/data/handbook/index.cfm. I can't find an Hg-Ar peak to match the 1480 nm data line, so we will always have that peak unmatched. The Kr 1533.4 nm peak is slightly outside the acceptable range for each day, so we may have to increase the pass threshold for the SWIR. This seems reasonable considering the spectral resolution is so much lower than the VNIR. Best results for the 3 days are:

    44
    55Day 1: -0.783447 and -5.263965    8 pass, 1 fail (VNIR changed because O file named wrong initially)
    6 Day 2: -0.488281 and -4.894000    4 pass, 2 fail
    7 Day 4-1 -0.125000 and -5.484375   5 pass, 1 fail
    86
    9 Day 1 seems by far the best day to continue with. Remember these differences are on the original wavelength scales, not last years.
