Bases:
sourcefinder.accessors.casaimage.CasaImageUse casacore to pull image data out of a CASA table as produced by AMI-LA.
- Parameters:
- urlstr
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). If not supplied, an attempt is made to read them from the header.
Notes
AMI-LA does not currently include image duration in its headers, so a placeholder value of 1 is used.
The start time is taken from the CASA coords record and may not be valid if the image is composed of multiple observations.
