Comparison between the observed and the RADEX-MCMC best-fitted model parameters(a) predicted HeH+ line fluxes.
| HeH+ Lines (υ′, J′) → (υ, J) | Rest wavelength (μm) | Upper state energy / kg (K) | Observed line flux (10−18 Wm−2) | Predicted line flux (by RADEX-MCMC)W (10−18 Wm−2) | Ratio (Observed / Predicted) |
|---|---|---|---|---|---|
| (0,1 → 0,0) | 149.091 | 96.5 | 163 ± 32 | 171.60 | 0.95 ± 0.186 |
| (1,0 → 0,1)[P(1)] | 3.51532 | 4188.3 | 1.55 ± 0.16 | 1.80 | 0.86 ± 0.089 |
| (1,1 → 0,2)[P(2)] | 3.60677 | 4276.9 | 2.08 ± 0.31 | 1.92 | 1.08 ± 0.161 |
Notes. (*)RADEX line flux is given erg s−1 cm−2. To compare with the observed flux, we convert the RADEX flux unit to W m−2 and accounting for the observational angular sizes (see notes in Table 3). (a)RADEX-MCMC best-fitted model parameters from Table 6: Tkin = 2455 K, n(e) = 1.45 × 105 cm−3, n(H) = 6.61 × 104 cm−3, N[HeH+] = 2.04 × 1012 cm−2, line width = 30 km s−1.
