The correlation of two atmospheric Cerenkov techniques for studying cosmic-ray shower development

Abstract
A comparison of the lateral distribution function and the pulse time profile of Cerenkov light from individual cosmic-ray showers shows good correlation between these parameters for showers with sizes around 106 particles at sea level. This is as would be expected if both parameters reflect the pattern of shower development in the atmosphere. The relationship between them is not in good agreement with a theoretical relationship developed for larger showers.
