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). Columns (4) and (5) list the kinetic temperature (Tk) and hydrogen density (nH), respectively, of the gas. Column (6) lists the depth of the layer in AV-units.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
