  Xova is a software package that implements baseline-dependent time and
channel averaging on Measurement Set data. The uv-samples along a baseline
track are aggregated into a bin until a specified decorrelation tolerance is
exceeded. The degree of decorrelation in the bin correspondingly determines the
amount of channel and timeslot averaging that is suitable for samples in the
bin. This necessarily implies that the number of channels and timeslots varies
per bin and the output data loses the rectilinear input shape of the input
data.
