Tutorials
VLA datasets updated September 27th
Here you find instructions for the tutorials to be presented, if you want to follow along. Ideally, you have a Linux Laptop (or virtual machine) with Red Hat 8 or equivalent distribution, see compatibility matrix for CASA here.
You want to make sure you download any required software and datasets in advance and, if possible, test their functionality. If you run into any issues, you can contact the NRAO helpdesk (help.nrao.edu) or bring it up during the general discussion sessions with NRAO staff during the CDE.
The following software packages are required:
- CASA (6.4.1 recommended; see https://casa.nrao.edu)
You can download either of the pipeline versions: ALMA or VLA.
The tutorials should generally also work with the latest general use CASA 6.5.6, which is recommended for the VLA spectral line tutorial. If you are able to have both versions available, that would be ideal. - CARTA (see: https://cartavis.org/#download)
- Optional (for advanced users): Jupyter (https://jupyter.org/install) with modular CASA (see instructions here)
The following datasets are required to be downloaded:
- ALMA: https://bulk.cv.nrao.edu/almadata/public/working/sis14_twhya.tgz (1.9 GB)
Additional instructions for download of this dataset can be found here. - VLA: For start of the calibration use: https://casa.nrao.edu/Data/EVLA/IRC10216/reduced_10s.ms.tgz (1GB)
After calibration and uvcontsub applied you can use: https://casa.nrao.edu/Data/EVLA/IRC10216/irc10216.ms.contsub.tgz (300 MB)
Calibrated image cubes: https://casa.nrao.edu/Data/EVLA/IRC10216/irc10216_full.tgz (120 MB)
Additional instructions for download of the main dataset can be found here.
