During Expedition 378, a software error resulted in an overwrite of the NGR calibration file. As a result, all 
core sections measured used an incomplete calibration file, and the NGR calibration files in LIMS are missing the
slope and intercept for channel to energy conversion. While missing energy conversion information does not affect
data reduction and reported counts/sec, threshold channel number picks can affect the data reduction on reported 
counts/sec in LIMS. Core sections were run with threshold channel numbers either one higher or the same as would 
have been picked by hand using a complete calibration, and even though picks of neighboring channels have a 
statistically insignificant impact on the overall data, concentration studies require a complete set of 
calibrations. A complete calibration file set is available here.
