AbstractWe have proposed elsewhere a photoelectric technique for narrow field astrometry which is potentially far more accurate than photography. In this paper the atmospheric limitations, particularly those arising from anomalous refraction are studied. The conclusion is that considerable improvements are indeed feasible from the ground.
