CRITICAL TABLES FOR CORRECTING OBSERVED ALTITUDES FOR ATMOSPHERIC REFRACTION IN POLAR LATITUDES

Abstract:	It has been customary for years to prepare refraction tables for some standard conditions, say a temperature of 50 degrees F. and a barometric pressure of 30 inches. Where precision was required, auxiliary tables were offered, allowing for the correction to other temperatures and pressures. Since in the past most of the navigating has been done in temperate latitudes, it has been considered sufficient to offer a single table of refraction corrections suitable for average conditions in those latitudes and to omit the auxiliary tables. Also, it has been sufficient to include corrections only for altitudes from 8 to 90 degrees.
