Total direct collisional ionization rate coefficient

1st line gives the temperatures (in K) at which the rate coefficients have been calculated.
Remaining lines have the format: initial level before ionisation, final level after ionisation, ionisation potential of initial level in eV, collisional ionisation rate coefficients in cm^3 s^-1 using a Maxwellian distribution at each given temperature
