Getting Help and Contact Information

The primary portal to get help from CASA and NRAO staff on issues you might encounter is through the Helpdesk:

• Registered NRAO Interactive Services users can access the CASA HelpDesk through the my.nrao.edu portal (use the CASA Release tab and then the Helpdesk sub-tab).
• For internal NRAO and ALMA/EVLA project users, CASA uses JIRA as its issue tracking system. Registered NRAO JIRA users can submit issues and maintain contact with CASA until resolution.
