Re: How to determine which CalDB version you already have installed
Sounds like a fine idea to me.
See the web page http://cxc.harvard.edu/caldb/downloads/index.html under
"Determining your current CalDB version". There is a rather long, but
easily buffered/pasted "dmlist" command posted there that will address
this issue. Also, I have added the same command to the introduction
section of the "upgrade" README file. (Those using the "main" tar-ball
don't have to worry about this--it just clobbers everything and updates
the CalDB regardless of previous version.)
Here is the command for everyone's sake, which will work if you have
previously loaded CIAO:
unix% dmlist \
$CALDB/docs/chandra/caldb_version/caldb_version.fits"[cols CALDB_VER]" \
data,clean | tail -1
This would be a fine command to alias to something like "get_caldbver"
in a .cshrc file.
