Abstract
The instrument gives a continuous photographic trace of the logarithm of intensity against time which is integrated to an energy figure by photometric means, an optical wedge being used to reduce the logarithm to intensity. A brief comment is made on the results obtained over a period of 9 yrs.This publication has 0 references indexed in Scilit:
