SPC header items

The following is a list of header information contained in the SPC registers. These items can be examined with STATISTICS or EDIT, and plotted with XYPLOT. They are located just after the 8196 spectral channels in each register; the locations are listed below. A list of header locations can also be obtained on-line with the EDIT command.
