Visibility

class xrayvision.visibility.Visibility(vis, *, u, v, offset=<Quantity [0., 0.] arcsec>, phase_centre=<Quantity [0., 0.] arcsec>)

Bases: object

Generic Visibility object.

Parameters:

• vis – Array of N complex visibilities sampled at the u, v coordinates.

• u (Annotated[Quantity, Unit("1 / arcsec")]) – Array of u coordinates where visibilities are sampled.

• v (Annotated[Quantity, Unit("1 / arcsec")]) – Array of v coordinates where visibilities are sampled.

• phase_centre (Annotated[Quantity, Unit("arcsec")] | None) – Phase centre of the visibility, defaults to (0,0).

• offset (Annotated[Quantity, Unit("arcsec")] | None) – Offset of the phase_center visibility, defaults to (0,0).
