Parameters of the default radiative-transfer models and the assumption differences in the alternative fits.
| Model | Assumptions |
|---|---|
| D | default case, τ(250 μm)∕τ(J) = 1.0 × 10−3, β = 1.8 |
| P | kISRF fitted using pixels with highest 3% of N(H2) only |
| W | LOS cloud extent adjusted pixel by pixel |
| ΔAV | external field changed by AV = ± 1 mag |
| K | τ(250μm)∕τ(J) = 2.0 × 10−3, β = 2.1 |
| TD | dust changes with density from D to K assumptions |
