new asca gis calibration files

[zellar@timaeus.gsfc.nasa.gov (Ron Zellar)]

Two new ASCA GIS calibration datasets are available in the HEASARC
Calibration Database.  The datasets are located in the files:

/caldb/data/asca/gis/bcf/gis2_ano_on_flf_180295.fits
/caldb/data/asca/gis/bcf/gis3_ano_on_flf_180295.fits

and contain the ASCALIN_FLF datasets valid for the GIS2 and GIS3
instruments respectively.  The datasets provide updated gain maps and were
delivered to the Calibration Database by Eric Gotthelf and Ken Ebisawa of
the ASCA GOF through cooperation with the GIS team.

These datasets supercede the ASCALIN_FLF datasets distributed on April 20,
1994 which are valid for observations made after April 4, 1993.
