Returns the proper motion for specified source. See also radialVelocity, restFrequency, and transition.


au.properMotion(vis, source, spw=''. arcsecPerYear=True)
  • source: can be integer ID or string name
  • spw: should not matter, but the values in the table are per spw
  • arcsecPerYear: if False, then radians/second; if True, then arcsec/year


CASA <5>: au.properMotion('',source='TW Hya')
  Out[5]: array([-0.06689857, -0.01235974])  # arcsec/year
