<task type="function" name="msuvbin" category="ms, averaging">
<shortdescription>grid the visibility data onto a defined uniform grid (in the form of an ms); multiple MS\'s can be done onto the same grid</shortdescription>
msuvbin is a uv gridding task. The use is for large volumes
of data (from multiple epochs) that needs to be imaged into
one image. One way of proceeding is to image the epochs and
average them after wards. Rather than doing this averaging
the visibilities on a common uv grid has several convenience
advantages like easily doing the proper weighted averaging and imaging.
If an output grid already exists and a second ms is gridded on the grid
then the output grid parameters is ignored but the existant grid is used.
