Howard and Kaike,
I checked all of the frames and gangs on files1 from last night, and
they all look good.  As such, I believe that the fix for PR6846 was a
success.
When we spoke last night, you mentioned a concern that astro files
showed some checksum errors.  I believe that the ones that you saw were
associated with the initial frame from each DA board.  These files just
have header information (no FITS data) and do not have any checksum
headers by design.  This confusion was my fault in that I should have
listed a better validation command in my shake request.  The following
command will run the checksum analyzer on each of the astro gang files,
filter out those with valid checksums (0xffffffff), and and filter out
those that have no checksum headers:
ls -1 *.fit | xargs -n 1 /home/products/.biery/fitsChecksum | grep -v
'0xffffffff' | grep -v 'characters = 8640'
If you have any questions or need more information, please let me know.
Thanks for your help with this,
Kurt
