Table 2
Number of stars in our analysis with problematic χ2 distributions of wind strength (log Q), effective temperature (Teff), helium abundance (Y(He)), and surface gravity (log g) caused by degeneracies or because they reach the boundaries of the grid.
| Parameter | # stars | Comments |
|
|
||
| log Q | 69 | Limitations from the Hα and He ii λ4686 diagnostics |
| Teff | 20 | Strong nebular contamination and/or weak or nonexisting He i lines, improved by HHeN diagnostics |
| Y(He) | 14 | He abundance too low – possible undetected binarity |
| log g | 10 | Gravity too high – possible undetected binarity |
