Physical parameters explored in single point models and their fiducial values.
| Parameter | Symbol | Range or value | Fiducial |
|---|---|---|---|
| Density | nH | 105–3 × 1012 cm−3 | 109 cm−3 |
| Temperature | TK | 200–5000 K | 1000 K |
| Dust fraction | Q∕Qref | 0–1 | 0 |
| FUV field(a) | G0 | 104 | 104 |
| Visible field(a) | Tvis | 4000 K | 4000 K |
| Visible dilution(a) | W | 5 × 10−7 | 5 × 10−7 |
Notes. (a) The mean intensity of the radiation field is given by 
, where
Bν (Tvis) is the intensity of a black-body radiation field at a temperature Tvis
and 
the FUV part of the ISRF rescaled by G0
(see Appendix A).
