phaserotate_visibility

ska_sdp_func_python.visibility.base.phaserotate_visibility(vis: Visibility, newphasecentre: SkyCoord, tangent=True, inverse=False) → Visibility

Phase rotate from the current phase centre to a new phase centre.

If tangent is False the uvw are recomputed and the visibility phasecentre is updated. Otherwise, only the visibility phases are adjusted.

Parameters:

• vis – Visibility to be rotated

• newphasecentre – SkyCoord of new phasecentre

• tangent – Stay on the same tangent plane? (True)

• inverse – Actually do the opposite

Returns:

Visibility
