The accompanying tables list predicted H2 level column
densities for an updated grid of C-shock models.
It improves upon the work of and supersedes the tables in
Wilgenbus et al. (2000, A&A).
Each table refers to one preshock density, and contains
models for shock speeds ranging from Vmin = 10 km/s up to
the critical velocity Vcrit at which the shock becomes J-type.
n3v10-v80.dat: nH = 1e3 cm-3 (Vcrit = 80.8 km/s) V=10 to 80 by 10 km/s
n4v10-v70.dat: nH = 1e4 cm-3 (Vcrit = 70.0 km/s) V=10 to 70 by 10 km/s
n5v10-v49.dat: nH = 1e5 cm-3 (Vcrit = 49.0 km/s) V=10,20,30,40,49 km/s
n6v10-v30.dat: nH = 1e6 cm-3 (Vcrit = 31.5 km/s) V=10 to 30 by 10 km/s
n7v10-v23.dat: nH = 1e7 cm-3 (Vcrit = 23.1 km/s) V=10,15,20,23.1 km/s
The tables are laid out as follows:
-----------------------------------------------------------------
* Line 1: initial values of nH, B, and atomic H abundance n(H)/nH.
* Line 2: Values of Vshock in km/s, shown above the relevant columns.
* column 1: V quantum number of the level
* column 2: J quantum number of the level
* column 3: Energy of the level above the gound state, in Kelvin
* column 4-X: Natural logarithm of the H2 column density in level (V,J)
integrated perpendicular to the shock front, and
normalized by the statistical weight (2S+1)(2J+1) of the level,
where S=0 for even J (para-H2), and S=1 for odd J (ortho-H2).
