Left panel: Number density profiles per cubic centimeter as a function of height in kilometers computed using the distribution of heating events γ₁(T) given by Eq. (23) (solid), γ₂(T) given by Eq. (24) (dashed) and γ₃(T) given by Eq. (25) (dotted). Blue lines correspond to A = 1, red lines to A = 0.1, green lines to A = 0.01, and purple lines to A = 0.001. Right panel: temperature profiles T[K] as functions of the height expressed in km. The profiles are computed for the same distribution functions of the left column. Moreover the same colour coding and line style has been used.
