Notes. Column (1) lists the model number. Columns (2) and (3) list the cosmic-ray ionization rates (ζ) and radiation fields (χ), respectively, in units of their standard Galactic values (ζ0 = 5 × 10-17 s-1 and 1 Draine field ≡ 2.74 × 10-3 erg s-1 cm-2). Column (4) lists the hydrogen gas density (nH). For the PDR models the temperature varies with depth and is not listed.
