Obtaining the CASA Release

Supported Operating Systems


The latest CASA release 3.3.0 is available for the following operating systems:

  • Linux
    • RedHat 5.5 (32-bit & 64-bit)
    • Fedora 14 (64-bit)
    • Ubuntu 10.10 (64-bit)
  • Mac OS
    • Mac OS 10.6 (Snow Leopard)
    • Mac OS 10.7 (Lion)
CASA may also work on other flavors of Linux. The list above covers those operating systems that we run regular tests on. From CASA 3.3 and upwards we do not support Mac 10.5 (Leopard) anymore. Please download CASA 3.2.1 for that operating system or, even better, upgrade your Mac to 10.6 or higher.


Hardware Requirements


The hardware requirements to successfully run CASA depend critically on the datasets that are worked on. Please see our EVLA and ALMA data processing hardware recommendation sites.


Downloads


Please follow these links for downloading the code for your specific operating system and for the installation instructions. Note that, if possible, you should run CASA on a 64bit computer for better performance.
We also provide links to intermediate, Stable versions, which pave the way for the next, following release. They have additional functionality over the current release but Stables are not as rigorously tested as the release and they likely contain developments that are not yet complete. All available documentation is only for the release, so Stable may behave somewhat differently than what is currently documented.

The latest CASA release is 3.3.0 (r16856, Nov 4, 2011)
