  • Mac OS X
    • OS X 10.10 (Yosemite; 64-bit)

CASA-based Pipelines


ALMA and VLA pipelines are updated regularly and included in some versions of CASA. In the download section below, the latest official pipeline releases are available that are being used for production at the observatories.



Downloads


Please follow these links for downloading the code for your specific operating system. Installation instructions are provided, too.
CASA Stables and Monthlies are code under development. Use with caution as the code is still undergoing changes, is less tested and not well documented.
