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.
