You've got your archived OSSE dataset onto a VAX with IGORE installed. You have either FTPed directly from the archive or you downloaded from W3Browse onto a Unix system, un-tarred the W3Browse archive file, then FTPed the resulting files to the VAX.
By either of these routines, the compressed (gzipped) files on your system should end with a designator of the form $5NGZ. To go from these compressed FITS files to the SDB files which IGORE requires, we have a simple command:
osse_unpack [directory name] [FITS|SDB|BOTH]where [directory name] is the FULL VMS path to the files you downloaded from the archive, and [FITS|SDB|BOTH] specifies the format option of the final files. The final result can be in FITS (the only option if you run this routine on Alpha VMS), SDB files (which is required for processing in IGORE) or BOTH. This routine un-gzips the files to FITS, then (optionally) converts them to SDB. Non-FITS files from the archive are also handled by this routine.
From here, your next stop is IGORE...
