Analysis Packages

The two main analysis packages used for the processing of VLA data are AIPS and CASA.

CASA

 Common Astronomy Software Applications (CASA) package is a set of C++ tools bundled together under an iPython interface as a set of data reduction tasks. The CASA collaboration is led by the National Radio Astronomy Observatory, with the primary goal of supporting the data post-processing needs of ALMA and the VLA. The CASA tasks are oriented towards end-user data processing and analysis, while the toolkit is geared towards the support of algorithm development and the construction of tasks.

AIPS

 The Astronomical Image Processing System is a software package from the National Radio Astronomy Observatory that is used for calibration, data analysis, imaging, image display, plotting, and a variety of ancillary tasks on astronomical data (primarily radio data). Strategies for VLA data reduction using AIPS can be found in the AIPS CookBook.

Connect with NRAO

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
