This directory tree contains data that in reduced to a standard file
type (which I have not yet decoded).  Note that there is no
description of the data in these files, only a reference to the
original "raw" data file name.  We hope to put together a better
directory of this data before long.

Generally, the first two letters of the scan name denote the element
being probed in a sample. The subdirectories are arranged by the first
letter of the scan name.
