Energy levels, transition frequencies and Einstein A coefficients were taken from JPL. The Einstein A coefficients have been re-scaled using a dipole moment of 3.27 D. The collisional rates are taken from Chandra & Kegel (2000) and were calculated for temperatures in the range from 10 to 120 K including energy levels up to about 82 cm-1 for collisions with H2. At present no extrapolated rates are made available.
