get_stokes_from_vis_data

pyvisgrid.core.stokes.get_stokes_from_vis_data(vis_data: Visibilities, stokes_comp: str, polarization: str) → np.ndarray

Get the Stokes visibility for a given Stokes component depending on polarization.

Parameters:

vis_datapyvisgen.simulation.Visibilities

The Visibilities which are the output of the pyvisgen.simulation.vis_loop function.

stokes_compstr

The name of the Stokes component which should be returned. Valid names are: 'I', 'Q', 'U', 'V', 'I+V', 'Q+U', 'Q-U', 'I-V'.

polarizationstr

The type of polarization which should be considered. Valid values are: 'circular' and any value. In case this is not set to 'circular', the result will be the same for all other values.

Returns:

numpy.ndarray:

The Stokes visibility of the given Stokes component with the given polarization.
