CASA, the Common Astronomy Software Applications, serves as the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and Karl G. Jansky Very Large Array (VLA), and is often used by other radio telescopes.
The CASA organization on GitHub contains prototype packages that the CASA team is developing for the next generation of radio telescopes (such as the ngVLA and ALMA WSU), along with other ancillary packages related to production CASA (such as documentation). The production CASA code is hosted on Bitbucket.
These prototype packages are still under development and will be rapidly changing, however, some have progressed to the stage where tutorials are available.
