It supported advanced algorithms such as multi-scale CLEAN and OTF (On-The-Fly) mosaicking, which were revolutionary for wide-bandwidth radio imaging at the time. Core Tools for Users It supported advanced algorithms such as multi-scale CLEAN
While newer versions (e.g., 6.x) are now standard, 4.2.1 is frequently cited in archival research for reducing data from major projects like the Cartwheel galaxy mosaic and ALMA ACA core surveys .
The filename refers to a compressed distribution of the Common Astronomy Software Applications (CASA) , version 4.2.1 . This software is the primary data processing suite used by the international radio astronomy community, particularly for the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G.
