Collisional excitation of H2 by grains in C-type shocks

G. Pineau des ForÍts et al (2001, MNRAS, 323, L7).  Probabilities of excitation and dissociation of ortho-H2 (OH2GR.DAT and dissociation_ortho-H2) and para-H2 (PH2GR.DAT and dissociation_para-H2) are given for H2 - surface impact velocities v (impact) = 2(2)50 km s-1 (impact_velocities).
