% eta = AirPartition(E, h, i)
%
% AirPartition.m returns the fractions of energy deposited into different
% excitations and the "fast heating" process in air (N2: 78.11%, O2:20.91%,
% Ar: 0.98%).
%
% eta - fraction of energy deposited into the process given by i
% E - electric field (V/m), which can be a scalar or column vector
% h - altitude in km (h>150km is intepreted as neutral density in cm-3)
% i - integer parameter specifying fractions to be calculated:
% 1 elastic collisions of O2
% 2 elastic collisions of N2
% 3 elastic collisions of Ar
% 4 excitation of rotational energy levels of O2
% 5 excitation of rotational energy levels of N2
% 6 excitation of vibrational energy levels of O2
% 7 excitation of vibrational energy levels of N2 (eta_V)
% 8 excitation of electronic energy levels of O2
% 9 excitation of electronic energy levels of N2
% 10 excitation of electronic energy levels of Ar
% 11 ionization of O2
% 12 ionization of N2
% 13 ionization of Ar
% 14 attachment to O2
% 15 fast heating process (eta_T)
% eta_T = eta_ela_O2 + eta_ela_N2 + eta_ela_Ar +
% eta_rot_O2 + eta_rot_N2 + eta_vib_O2 +
