Note
A cache of measurement sets for recently observed scheduling blocks is kept on the Galaxy Lustre file system at the following paths: /scratch2/askap/askapops/beta-scheduling-blocks (for BETA data) and /scratch2/askap/askapops/askap-scheduling-blocks (for ASKAP/ADE data) - You may wish to check there first as access to this location is faster than access to the commissioning archive, where the files may reside on tape media.
The archive can be accessed from Galaxy via a command line utility called ashell.py. This can be loaded manually using:
module load ashell
You can add this to .bashrc for automatic loading; see the section “Setting up your account” in the Central Processor Platform documentation page. Once loaded you can start the interface with:
ashell.py
After starting ashell you should be presented with the the following prompt:
pawsey:offline>
To download the scheduling block 50 data to your current folder use the following commands:
pawsey:offline>login
pawsey:online>get /projects/ASKAP Commissioning Data/beta-scheduling-blocks/50.tar
Ashell uses the concept of remote and local folders, the remote folder is the directory where the files are located in the archive, this is set by the ‘cf <path>’ (Change Folder) command, you can check the current remote folder with the ‘pwf’ (Print Working Folder) command. The local folder is set by the ‘cd <path>’ command and can be checked with ‘pwd’.
Quick help is also available via ‘help’ and ‘help <command>’
