Table 2

Column integrated intensity (C-Int-Int) of the main lines and bands in kR units. Values are presented for different mean energy of a mono-energetic electron distribution considering a fixed total energy flux of 1 erg · cm⁻² · s⁻¹ (which means a number of particles multiplied or divided by 10 for a mean energy of 10 and 0.1 keV respectively). For molecular lines, the values for the full band (FB) are given except for the 1st negative bands of ${\mathrm{N}}_2^{+}$. The numbers in parentheses are the C-Int-Int obtained at constant number of particles compared to the case of 1 keV and 1 erg · cm⁻² · s⁻¹ (which corresponds to a total energy flux of 10 and 0.1 erg · cm⁻² · s⁻¹ respectively)
