CASA processing of VLBI observations

The CASA package is now capable of calibrating the majority of VLBI observations. The new tasks and functionalities to process and calibrate VLBI observations – whose implementation has been led by JIVE – are described in a paper published in the Publications of the Astronomical Society of the Pacific (PASP) journal. In addition to a description of the software, a comparison with AIPS processing is included, demonstrating the results are virtually identical. This paper appears jointly with the new CASA reference paper, which gives a high-level overview of the entire CASA package.

The Common Astronomy Software Applications (CASA) software package is a data processing software used for different radio telescopes. It is the main processing package for instruments such as the Atacama Large Millimetre/submillimetre Array (ALMA), and the Karl G. Jansky Very Large Array (VLA). The CASA software can process data from both single-dish and aperture-synthesis telescopes.
