EU ARC CASA Tutorial for ALMA Cycle 2 PIs

Cycle 2 PI Tutorial Hands-on session 1a

Programme

All lectures and the advanced hands-on sessions will take place in room Telescopium (a.k.a. "Old Auditorium").

The beginner's parallel hands-on sessions will take place in room Fornax (a.k.a. "Old Council Room").

Please note that for detailed help with the analysis of your own ALMA data, you have the opportunity to visit your ARC node for face-to-face support. Due to the limited number of tutors, we will not be able to provide extensive data reduction support for individual projects. However, short questions are of course welcome.

Hardware needs

You will need to bring a reasonably powerful laptop to participate in the hands-on sessions:

Minimum requirements:

dual-core processor
3 GB RAM
150 GB free space on your hard disk (reduced from previously 300 GB)
- External disks are too slow for data processing! You need to have the empty space on your internal hard disk.
- If you don't have that much free space, use an external disk before you visit ESO to temporarily move out data which you don't need for the workshop. When you return home, you can move it back in.

CASA 4.2.2 with pipeline installed (and tested to work; refer to the CASA download page

for details on what operating systems are supported)

CASA 4.2.2 with pipeline is available for Linux and OSX and is marked as "ALMA pipeline version" on the CASA download page
- direct link to the Linux version download: casapy-42.2.30986-pipe-1-64b.tar.gz
- directl link to the OSX version download: CASA-intel64b-10.8-30986-pipe.dmg

in order to test whether you have the right version of CASA installed, do the following

start casapy by typing

              casapy --pipeline --nologger

in your terminal you should see among other startup messages

              CASA Version 4.2.2 (r30986)

once the startup is complete, type

              inp hif_restoredata

That should result in the following output

       --------> inp(hif_restoredata)
       #  hif_restoredata :: Restore flagged and calibration interferometry data from a pipeline run
       vis                 =       ['']        #  List of input visibility data
       session             =       ['']        #  List of sessions one per visibility file
       products_dir        = '../products'     #  The archived pipeline data products directory
       copytoraw           =       True        #  Copy calibration and flagging tables to raw data directory
       rawdata_dir         = '../rawdata'      #  The rawdata directory
       pipelinemode        = 'automatic'       #  The pipeline operating mode
       async               =      False        #  If true the taskname must be started using hif_restoredata(...)

if you get an error message instead, you have installed the CASA version which does not contain the pipeline. In this case, please delete your installation and install the version with pipeline instead.

Data to download before you arrive at ESO

In this location we will enumerate all the data (as it becomes available) that you will need download if you want to participate in one or several of the hands-on sessions (see programme). Notifications on when new data is ready for download will be sent by email to all participants. The data will remain online for at least several months after the workshop.
