The CASA Software for Radio Astronomy: Status Update from ADASS 2020

CASA, the Common Astronomy Software Applications package, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and NSF's Karl G. Jansky Very Large Array (VLA), and is frequently used also for other radio telescopes. This poster gives an overview of several exciting recent developments. With the arrival of CASA 6, users now have the option to download CASA through a modular pip-wheel installation, giving them the flexibility to integrate CASA into their personalized Python environment. Another major new development is the introduction of a new task for joint deconvolution of single-dish and interferometry data. This has been a major priority for our user base, and a growing number of test-cases reveal that this algorithm provides a great improvement in combining single-dish and interferometry data. We briefly also highlight the CARTA visualization software, and summarize the proto-type development of a next-generation CASA software and related infrastructure for future radio facilities, such as a Next-Generation VLA.
