In July of 1996, a processing problem caused the orbit files to not be
updated with recent versions from ISAS.  This problem was noticed and
corrected on February 3, 1997.

The orbit files contain a time history of ASCA's orbital parameters and
are used to calculate various quantities in the filter (.mkf) files.
Using an out of date orbit file can cause good time intervals for things
like earth occultation, SAA passage, etc. to be slightly incorrect.

The processing team has re-created all of the filter files which were 
distributed with this problem. If you have data observed after July 1996
and  processed before February 1997, we recommend that you obtain a new
filter file by anonymous FTP from

	ftp://ssvs.gsfc.nasa.gov/pub/outgoing/stage/new_orbit_mkf

Below is a list of affected sequences.

There is an HTML version of this message at

with links to the corrected version of each filter file.
