This routine adjusts the unfiltered event files to correct for
various spacecraft problems.
Currently there are two such problems.
First, between Feb 10, 1994 and Apr 8, 1994 some of the
GIS3 PHA telemetry bits were stuck in the "on" position.
The data from this period can be recovered, but with
some loss of spectral resolution.
The second problem is that occasionally the spacecraft is
switched into FAST mode before it is switched from 4 CCD
to 1 CCD mode. Data is actually taken on one CCD
(no guarantee that it is the correct one), but
the FITS keywords show 4 CCD mode. The fast4fix STOOL
adjusts the keywords to reflect the actual mode.
As of Feb 6, 1996, this only significantly affected three
sequences: 10010160, 40011000, and 41010000.
