Atmosphere

class showermodel.atmosphere.Atmosphere(h0=2.2, h_top=112.8292, N_steps=550, model=1)

Bases: DataFrame

DataFrame containing an atmosphere discretization.

Use sm.Atmosphere() to construct the default Atmosphere object.

Parameters

h_top (float) – Top level of the atmosphere in km above sea level.
N_steps (int) – Number of discretization steps.
model (int) – CORSIKA atmospheric model. Presently either 1 or 17. More models to be implemented.
