Estimation of the horizontal component of astronomical refraction in an ellipsoidal atmosphere.
Abstract
An algorithm of computation of vertical and horizontal components of astronomical refraction for the homogeneous ellipsoidal Earth atmosphere is presented. For the atmosphere ellipsoid with parameters determined from the measurements of the vertical component near the horizon maximum the value of the horizontal refraction component is 0.1arcsec for the zenith distance 88°. The real atmosphere is approximated by a three-axial ellipsoid with the atmosphere maximum slope about 0arcmin.3 at the zenith.
