.. py:class:: Kat7CasaImage(url, plane=0, beam=None)

   Bases: :py:obj:`sourcefinder.accessors.casaimage.CasaImage`


   
   Use casacore to pull image data out of a CASA table as produced by KAT-7.

   Note that KAT-7 does not currently include image duration in its headers,
   so we use a placeholder value of 1.

   Note also that the start time is taken from the CASA coords record, and
   may not be valid if the image is composed of multiple observations.

   :Parameters:

       **url** : str
           Location of the CASA table.

       **plane** : int, default: 0
           If the data is a datacube, specifies which plane to use.

       **beam** : tuple, default: None
           Beam parameters in degrees, in the form (bmaj, bmin, bpa). If not
           supplied, the method will attempt to read these from the header.
