This dataset consists of three data directories containing, respectively,
tracked data cubes, power spectra, and mode parameter fits for the selected
active region and one or two comparison regions of low magnetic activity
at the same latitude within half a Carrington rotation.  The root directory
contains, in addition to this file, the map file used to ingest the dataset
into the DSDS and the ds.rdb and ingest_history files created by the ingest
process.

The track directory contains the tracked data cubes (FITS files), plots of
the k=0 signal and power spectrum (PostScript files), the history, errlog,
and mapfiles associated with the processing of each longitude, and the SOI
conformance files overview.fits and record.rdb.  The overview.fits file is
the one created by the most recent run of fastrack, so the values of the
calling arguments in its header and T_FIRST and T_LAST are not appropriate
for the dataset as a whole, but its conformance information is.  The
record.rdb does apply to the whole dataset.

The pspec directory contains the 3-d power spectra of the data in track.
The values of T_START, T_STOP, T_FIRST, and T_LAST in the headers of the
spectra and in the overview.fits file refer to only one of the tracked
cubes, the one most recently processed; but the values of T_REC and T_OBS
in the individual region spectra headers are correct.

The fits directory contains results of ringfits by one or two different
programs. Files named lat*lon* (with accompanying log.lat*lon*) are from
Stanford fits, those named fit.lat*lon* from Yale fits.
