Water line intensities across the Horsehead PDR.
| Line | Δα (″) | Line intensitya (K kms−1) | Line intensity (erg cm−2 s−1 sr−1) |
|---|---|---|---|
| o-H2O 110–101 | −40 | 0.024 ± 0.0036 | 4.25 × 10−9 |
| −20 | 0.105 ± 0.0039 | 1.86 × 10−8 | |
| 0 | 0.197 ± 0.0053 | 3.49 × 10−8 | |
| 20 | 0.210 ± 0.0044 | 3.72 × 10−8 | |
| 40 | 0.204 ± 0.0036 | 3.61 × 10−8 | |
| 60 | 0.135 ± 0.0053 | 2.39 × 10−8 | |
| o-H2O 110–101 | 0 | 0.222 ± 0.012 | 3.93 × 10−8 |
| p-H2O 111–000 | 0 | <0.066 | <9.3 × 10−8 |
Notes. Integrated line intensities and the corresponding uncertainties are computed over a 9.2–11.8 km s−1 velocity range, corresponding to the Horsehead. The value listed for the p-H2O line is a 3σ upper limit. aThe uncertainties quoted are statistical uncertainties computed from the rms noise in the spectra and do not include calibration uncertainties, which should be the same for all spectra.
