Module Contents

class sourcefinder.accessors.kat7casaimage.Kat7CasaImage(url, plane=0, beam=None)

Bases: 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:

urlstr

Location of the CASA table.

planeint, default: 0

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

beamtuple, 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.

tau_time = 1
