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

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


   
   A class to represent an AARTFAAC CASA image, extending the CasaImage class.


   :Parameters:

       **url** : str
           The location of the CASA table.

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

       **beam** : tuple, default: None
           Beam parameters in degrees, in the form (bmaj, bmin, bpa).

   .. py:method:: parse_frequency(table)

      
      Extract frequency-related information from the casacore
      table.

      This method overrides the implementation in the `CasaImage` class,
      which retrieves the entries from the 'spectral2' sub-table.

      :Parameters:

          **table** : casacore.tables.table
              The CASA table from which frequency information is extracted.



      :Returns:

          **freq_eff** : float
              The effective frequency (rest frequency) in Hz extracted
              from the casacore table.

          **freq_bw** : float
              The frequency bandwidth in Hz, derived from the WCS
              'cdelt' value in the casacore table.
