On the computation of new tables of the astronomical refraction.
Abstract
Since most observatories are situated at large altitudes above sea level it is natural to compile astronomical refraction tables for various heights above sea level. In the present paper, refraction values are calculated for the standard atmosphere at heights of 0.5, 1.0, 2.0, and 5.0 km above sea level. Values of the coefficient A are obtained from a comparison of refraction values computed for atmospheric models with identical vertical temperature distributions. Pressure at sea level is taken as 1013.25, 1080.0, and 910.0 mbar, and the pressure values at various heights are calculated from a barometric formula.
