Generic Visibility object.

Parameters:

• vis (astropy.units.quantity.Quantity) – Array of N complex visibilities sampled at the u, v coordinates.

• u (astropy.units.quantity.Quantity) – Array of u coordinates where visibilities are sampled.

• v (astropy.units.quantity.Quantity) – Array of v coordinates where visibilities are sampled.

• phase_centre (astropy.units.quantity.Quantity) – Phase centre of the visibility, defaults to (0,0).

• offset (astropy.units.quantity.Quantity) – Offset of the phase_center visibility, defaults to (0,0).
