The CASA Beta Releases
In October 2007, we began a staged Beta Release of the
Common Astronomy Software Applications (CASA) data reduction package.
This software is under development in support of the ALMA and EVLA
projects, but is intended to also be of general use for radio astronomy
data post-processing. This staged release allowed personnel
involved in the construction, operations, and advisory committees for
ALMA and EVLA to adopt early use of the package for commissioning,
development of user support capabilities, and to provide feedback to
the CASA team.
Through mid 2008, access to the Beta and support for CASA users
was restricted to ALMA and EVLA project personnel and key scientific
advisory committee members, due to limited user support
personnel. During this period the CASA team has concentrated on
completing the suite of basic functionality and pursuing advanced
algorithm development needed for ALMA and EVLA. In mid 2008, we are
expanding the availability of the Beta Release to others in the
community as our user support capabilities ramp up.
CASA remained in Beta Release until
least December 2009. During the beta release period, we provided
"patches" to the release at least twice a year in order to fold in
ongoing developments. Patches were also made as needed to fix any
egregious bugs. The first such "Beta Patch 1.0" was made available in
early April. The second patch ("Beta Patch 2.0") was made released
on July 7, 2008 (and was used for CASA tutorials at the June 2008 NRAO
Synthesis Summer school), with the third on December 1, 2008
("Beta Patch 3.0") and updated ("Beta Patch 3.1") on January 21, 2009.
The final beta release was ("Beta Patch 4" version 2.4.0)
issued on June 24, 2009.
Obtaining one of the old CASA Beta Releases
CASA is now in the non-beta release public release stage. Please
go to the obtaining the current release page for
instructions on how to obtain the current non-beta version of CASA.
If you wish to view documentation on previous beta releases, follow
the links to the Beta Patches on the left sidemenu of this page.
Your only recourse to getting old Beta Release versions is via the
svn repository:
Warning: If you are an external (to ALMA, EVLA, and NRAO) user and do not
register with the portal at my.nrao.edu, then you will have no
recourse for user support for the current version through the
helpdesk. WE STRONGLY RECOMMEND USERS OBTAIN CASA VIA THE PORTAL.
