Mkf bug fixed: replacement mkf files now available

Dear ASCA PIs:

Earlier this year, we reported a bug which appeared in mkfilter when the
program was updated for the REV1 version of the GSFC processing
pipeline. This bug caused good GIS data to be erroneously rejected when
ascascreen was run with its standard screening criteria.

Although a simple way around the bug was made available soon after the
bug was discovered, the bug itself has now been fixed. New, bug-free mkf
files have been generated for those sequences originally affected.

A list of affected sequences is appended to this message. If your
observation is on the list, you may, if you like, obtain a replacement
mkf file via anonymous FTP at legacy.gsfc.nasa.gov from the directory:


After replacing the the mkf file, you will be able to run ascascreen in
the usual way to obtain a full set of screened GIS data.

A WWW version of this message, with a link to the mkf files, is
available at the URL:
