apply_voltage_pattern_to_skycomponent

ska_sdp_func_python.sky_component.operations.apply_voltage_pattern_to_skycomponent(sc: SkyComponent | List[SkyComponent], vp: Image, inverse=False, phasecentre=None) → SkyComponent | List[SkyComponent][source]

Apply a voltage pattern to a SkyComponent.

For inverse==False, input polarisation_frame must be stokesIQUV, and output polarisation_frame is same as voltage pattern.

For inverse==True, input polarisation_frame must be same as voltage pattern, and output polarisation_frame is “stokesIQUV”.

Requires a complex Image with the correct ordering of polarisation axes: e.g. RR, LL, RL, LR or XX, YY, XY, YX.

Parameters:

  • sc – SkyComponent or list of SkyComponents

  • vp – voltage pattern as complex image

  • inverse – input and output polarisation frame (default False)

  • phasecentre – Phasecentre (Skycoord)

Returns:

List of SkyComponents
