ORAC-DR is best obtained by downloading the Starlink Software Collection. For those who have the most recent Starlink release, you can easily update ORAC-DR to take advantage of recent developments and bug-fixes.
The source code is available in a git repository. To update your ORAC-DR installation within your current Starlink installation, do:
% cd $STARLINK_DIR/bin/oracdr % git checkout master % git pull
Please note that ORAC-DR's development is closely tied to that of the Starlink Software Collection, so updating the pipeline without also updating the underlying Starlink code may cause the pipeline to stop working. If this is the case, visit the Starlink website for upgrade instructions, or email stardev@jach.hawaii.edu for assistance.
