Other features
In addition to the time histograms, Standard-1 files also contain
256-channel spectra from the internal calibration source, accumulated every 128 seconds. There are 30 columns of calibration spectra, one for each signal chain (the five PCUs have six signal chains each). And in common with other configurations in science array format, Standard-1 files have two additional columns called Spillage and ModeSpecific, as well as a coda of keywords summarizing EDS status.
