    89 The generated wavelength scale may be checked against the lamp lines to determine the error in each matching band and it's FWHM. The output of this test is recorded in the data analysis report. Any unrealistic FWHMs and any failing bands should be removed from the calibration and the wavelength scale regenerated.

    98 When you have created the final wavelength scale that passes the lamp line test, record the parameters on the ticket, especially the data set (day), sample_hdr_file and linefile from the config file and any optional parameters used with cal_spectral.py. Also record the final anchors and check that the VNIR and SWIR starting wavelengths are realistic. These may not match up with the anchors, depending on which sample header is used, as the previous calibration wavelengths are not currently set in the raw data files.

Also record the final anchors and check that the VNIR and SWIR starting wavelengths are realistic. The new wavelength scale is generated from the raw files and the offsets output by the script are from the raw files. As the previous calibration wavelengths are not currently set in the raw data files, you may need to set the SWIR offset to the previous offset to get good results.
