CASA, the Common Astronomy Software Applications for Radio Astronomy

Abstract CASA, the Common Astronomy Software Applications, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. This paper presents a high-level overview of the basic structure of the CASA software, as well as procedures for calibrating and imaging astronomical radio data in CASA.

• 1 Jansky Very Large Array (VLA), and is frequently used also for other radio telescopes.
• 2 The CASA software can handle data from single-dish, aperture-synthesis, and Very Long Baseline Interferometery (VLBI) telescopes.
• 3 One of its core functionalities is to support the calibration and imaging pipelines for ALMA, VLA, VLA Sky Survey, and the Nobeyama 45 m telescope.

This work deepens our understanding of the fundamental laws governing the universe, from subatomic particles to cosmic structures.
