About

CRUSH is an astronomical data reduction and imaging tool for select astronomical cameras, such as SHARC-2, LABOCA, SABOCA, PolKa, GISMO, SCUBA-2, SOFIA/HAWC+, and SOFIA/HIRMES. CRUSH is written entirely in Java, allowing it to run on virtually any platform. It provides the 'show' graphical tool for displaying FITS images, however reductions are normally run from the command-line. Further documentation and additional distribution formats are available from the CRUSH website.
