Query: The Parameterized Simulation of Electromagnetic Showers in Homogeneous
  and Sampling Calorimeters   A general approach to a fast simulation of electromagnetic showers using
parameterizations of the longitudinal and radial profiles in homogeneous and
sampling calorimeters is described. The dependence of the shower development on
the materials used and the sampling geometry is taken into account explicitly.
Comparisons with detailed simulations of various calorimeters and with data
from the liquid argon calorimeter of the H1 experiment are made.
