Table 3.
Model inputs excluding the species abundances.
| Parameter | Symbol | Range |
|---|---|---|
| Gas density | nH | 10–106cm−3 |
| Gas temperature | Tg | 10–104 K |
| Dust temperature | Td | 10–103 K |
| Radiation field | FUV | 10−1–105 Habing |
| Cosmic ray ionization rate | ζ | 10−2–105ζ0 |
| Total column density | N | 1015–1024 cm−2 |
| H2 column density | NH2 | 105–5 × 1023 cm−2 |
| C column density | NC | 1.0–1.5 × 1020 |
| Metallicity | Z | 10−2–100.5 |
Notes. ζ0 indicates a standard cosmic ray ionization rate of 1.3 × 10−17 s−1. It should be noted that throughout the text the UV field is discussed in units of the Draine field to facilitate comparison with other codes. However, Chemulator uses Habing (1 Draine = 1.7 Habing).
