Spectrophotometric Standards for the 1962 Total Solar Eclipse

Abstract

This report contains the information needed to make spectrophotometric measurements on the numerous 'jumping-film' spectrograms obtained at the total solar eclipse of 4 and 5 February 1962 at Lae, New Guinea, by a joint expedition of the High Altitude Observatory, the National Bureau of Standards, and the Sacramento Peak Observatory (AFCRL). It includes a brief description of the instrument, a catalog describing each of the spectrograms, characteristic curves for the photographic emulsions used, and a procedure for reducing photometric measurements to absolute intensity.
