Abstract

In this report a computation in Algol language for the optical air mass is presented. The method contains the reduction of the observation time, a daily correction for the solar declination and the trigonometric equation. By means of a modified Bemporad table with 900 entries the relative air mass is obtained. The running time for each observation is only 1/60".
