VLASS pipeline versions

VLASS makes use of the standard VLA calibration and imaging pipeline, though it is sometimes necessary to make pipeline versions that are only used for VLASS if there would be a delay in features needed for VLASS being placed in the regular VLA pipeline before they could be used. Most versions of the pipeline used for VLASS listed below are available from https://casa.nrao.edu/download/distro/linux/release/. Note that  since 2021 the pipeline versions have been built separately from the CASA build, hence we specify both the CASA and pipeline versions.

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.
