Δlog ( [M⊙ yr−1])(c,d) |
0.30 | 0.45 | 0.51 | 0.42 |
| Δlog(QHI,[s−1]) | 0.17 | 0.62 | 0.61 | 0.5 |

Notes. (a)The last column lists a rounded average from all three objects, indicating a “typical” systematic uncertainty margin arising from the different codes and methods. (b)Only accounting for methods where v sin i is not fixed. (c)Only incorporating values from methods that actually use the UV spectrum. (d)Sensitive to clumping constraints/choices, see Sects. 3.1.2 and A.2.
