Tom,

Actually, this is what I am going to do (write logfile info into fits
header).  I've already got the log file/fits headers parsed, and am
correctly matching times, so I'm going to continue and write the closest
temp into the fits header and the exposure length when known.  I'll also be
writing DARK/(whatever) to the headers based on mean/stdev info.  It'll be
based on Perl/CFITSIO/C, so anyone who can deal with those can use them.

Thanks,
Rob
