Beta Release

Hi, I'm Steve Myers, and I am the NRAO CASA Project Scientist. My job is to be the liason between the user communitiy, the NRAO projects, and the CASA development group. I lead various groups that provide scientific guidance to the CASA project, and help manage the project requirements.

This page contains information that I think will be helpful to users and those seeking information about the scientific aspects of the CASA project.

CASA News from the Project Scientist Interferometric Imaging

I have prepared a draft of a paper describing the process and challenges of Interferometric Imaging from the standpoint of signal processing. You can find a PDF version here.

If you are interested in learning more about interferometric imaging and data processing, NRAO hosted a Synthesis Imaging Summer Workshop held 10-17 June 2008 in Socorro, New Mexico. There was a CASA Tutorial given as part of the workshop.

Science Requirements

There are two main sets of Science Requirements for CASA, set by the ALMA and EVLA projects. These are what the CASA team works from during development.

 The CASA Beta Release

Beginning in October 2007, we have been implementing a staged Beta Release of the Common Astronomy Software Applications (CASA) data reduction package. This software has been under development in support of the ALMA and EVLA project, but is intended to also be of general use for radio astronomy data post-processing. This staged release will allow 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.

Initially, access to the Beta and support for CASA users was restricted to ALMA and EVLA project personnel and key committee members in order that the CASA development would not be burdened with user support and can continue to make progress to complete the suite of basic functionality and to pursue advanced algorithm development needed for ALMA and EVLA. During this period, CASA User Support Specialists were trained in the use of the CASA Beta Release, and in turn these specialists trained others as needed.

Starting with Beta Release Patch 2 in July 2008, the Beta Release was opened to the general community. See the Beta Release Page for more details.

The Beta Release is aimed at supporting basic interferometric data reduction. It will support the import of data in a limited number of formats, and a reasonably full set of processing capabilities for only a limited number of observing modes. See the beta release notes for more information on supported observing modes and data formats.
