CASA (Common Astronomy Software Applications) is a comprehensive software package to calibrate, image, and analyze radioastronomical data from interferometers (such as ALMA and EVLA, both shown below) as well as single dish telescopes. This wiki provides examples and hints for reducing data in CASA.
