Derived temperatures and statistical uncertainties at the emission peaks for ortho(o)- and para(p)-H2CO.
| Position | T (o-H2CO) | T(p-H2CO) |
|---|---|---|
| (K) | (K) | |
| IRAS 16293 A/B | 90.1 ± 4.4 | 62.4 ± 0.7 |
| E1 | 50.8 ± 3.8 | 36.4 ± 1.3 |
| E2 | 49.5 ± 7.8 | 34.1 ± 4.0 |
| W1 | 52.9 ± 5.1 | 34.8 ± 1.9 |
| W2 | 47.2 ± 7.8 | 31.3 ± 2.0 |
| HE2 | − | 34.0 ± 3.8 |
Notes. The values of para-H2CO are calculated by averaging the temperatures from both maps of para-H2CO. The minus (−) symbol for HE2 indicates that no bright emission from ortho-formaldehyde lines with higher upper level energies is detected at this position. Note that the calibration uncertainty of 20% is not considered in the stated uncertainties.
