RE: Notes on Disk Set 19

Hey Tom,

My current version of downfits takes file names on the command line.  It
does not create file names itself.  I thought that all version had done
this, but I may be wrong.  Can you tell me what you are passing as the
command line to downfits?

There was/is a problem with CFITSIO DLL's, in that the DATE-OBS time was off
by 1 hour (I'm sure related to DST garbage), but that was since removed, and
the DATE-OBS is grabbed from the plate files...

I think Michael is using a Linux compiled version of downfits.  If so, can
you (Michael), go into the tom.cpp file and uncomment the fits_write_date
function call to determine if this is a Windows only thing?

Later,
Rob
