libcasa-ms7 3.5.0-2ubuntu4 (amd64 binary) in ubuntu mantic

 The casacore package contains the core libraries of the old
 AIPS++/CASA (Common Astronomy Software Applications) package. This
 split was made to get a better separation of core libraries and
 applications.

 This package contains the data format for visibility data as described in the
 MeasurementSet definition. The MeasurementSet is where all data are
 ultimately to be found in CASA.
