VLASS pipeline versions
VLASS makes use of the standard VLA calibration and imaging pipeline, though it is sometimes necessary to make pipeline versions that are only used for VLASS if there would be a delay in features needed for VLASS being placed in the regular VLA pipeline before they could be used. Most versions of the pipeline used for VLASS listed below are available from https://casa.nrao.edu/download/distro/linux/release/. Note that since 2021 the pipeline versions have been built separately from the CASA build, hence we specify both the CASA and pipeline versions.
