Abstract
The shower simulation code CORSIKA has been used to investigate the electron
energy and angular distributions in high-energy showers. Based on the
universality of both distributions, we develop an analytical description of
Cherenkov light emission in extensive air showers, which provides the total
number and angular distribution of photons. The parameterisation can be used
e.g. to calculate the contribution of direct and scattered Cherenkov light to
shower profiles measured with the air fluorescence technique.
