EU ARC CASA Support

Local copy of the CASA software distribution

In case you have problems accessing the CASA repository at NRAO, the releases and the "monthly" and "stable" builds are available at this page:

General

There are several CASA support channels:

• The CASA home page, Using CASA (for all CASA users)
• The NRAO helpdesk (for all CASA users)
• The ALMA helpdesk (for CASA users wishing to analyse ALMA data)

In addition, the EU ARC and its nodes are offering CASA tutorials and face-to-face support.

Upcoming CASA Tutorials

• For tutorials at the EU ARC Nodes, please consult their local web pages.
