For detailed information regarding data processing refer to the CASA and AIPS documentation pages.

The following information addresses details specific to executing CASA or AIPS at the NAASC and lists additional reduction packages available at the the NMASC.


The current release version of CASA is the default with executing 'casa' or it's derivitives: casapy, casabrowser etc. Previous releases can be found at /home/casa/packages/RHEL6/release/casapy-<version>.  In addition typing casa -ls will show available versions of casa, and casa -r <version> to run a specific version.


AIPS is not supported by the NAASC, but the information below is given for completeness.

To use AIPS on the cluster users should have an AIPS specific Lustre data area and a personal .dadevs.always file in their home directory.  There are six predefined public lustre areas on both the NAASC and CV Lustre systems, but these are intended for temporary use and are periodically cleaned of old files.

To set your own AIPS data areas, do the following:

  cd                          # make sure you are in the home area
mkdir AIPS_1 # Create the directory touch AIPS_1/SPACE # Make an empty lock file (required) emacs -nw ~/.dadevs.always # Note the leading dot in the filename

(or use vi or gedit or your preference of editor). Then ensure this line is contained in the file:

  +  /lustre/naasc/observers/<username>/AIPS_1

The + sign MUST be in the first column, and there MUST be exactly two spaces between it and the leading slash in /lustre....
