class sourcefinder.accessors.aartfaaccasaimage.AartfaacCasaImage(url, plane=0, beam=None)[source]#

Bases: sourcefinder.accessors.casaimage.CasaImage

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

Parameters:
urlstr

The location of the CASA table.

planeint, default: 0

If the data is a cube, specifies which plane to use.

beamtuple, default: None

Beam parameters in degrees, in the form (bmaj, bmin, bpa).

parse_frequency(table)[source]#

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:
tablecasacore.tables.table

The CASA table from which frequency information is extracted.

Returns:
freq_efffloat

The effective frequency (rest frequency) in Hz extracted from the casacore table.

freq_bwfloat

The frequency bandwidth in Hz, derived from the WCS ‘cdelt’ value in the casacore table.
