[lsst-dm-stack-users] Running tasks on the LSST pipeline

[Robert Lupton the Good]

One thing to add is that in response to popular demand there's now also "processFile.py" (available from git at github.com:LSST-nonproject/obs_file.git) which allows you to process a single flat-fielded frame, e.g.

> $ processFile.py CORR00281173.fits --clobber-config

The output format could be tidier, but that's fixable.  Currently:
> $ ls rerun/rhl/CORR00281173*
> rerun/rhl/CORR00281173.fits
> 
> rerun/rhl/CORR00281173:
> background.fits                 icSrc.fits                      processFile_metadata.boost      src.fits
