Properties of select filamentary structures that are likely influenced by Cyg OB2.
| Filament | Width (pc) | Length (pc) | EM (pc cm−6) | ne (cm−3) | Q0/area (109 photons s−1 cm−2) | Q0 (1048 photons s−1) | M+ (M⊙) | DCygOB2 (pc) |
|---|---|---|---|---|---|---|---|---|
| CXR 9a | 5.3 | 8.0 | 5600 | 33 | 1.4 | 2.8 | 740 | 19 |
| CXR 9b | 4.6 | 14.9 | 5600 | 35 | 1.4 | 2.1 | 1100 | 15 |
| CXR 11a | 3.6 | 14.7 | 7500 | 46 | 1.9 | 1.7 | 880 | 34 |
| CXR 11b | 4.6 | 13.8 | 4200 | 30 | 1.1 | 1.5 | 880 | 47 |
| CXR 12 | 4.2 | 15.0 | 7800 | 43 | 2.0 | 2.4 | 1100 | 22 |
Notes. Width is the median FWHM of all profiles of the filament. Length is the by-eye estimate of the longest extent of the filament. EM is the median peak EM over all profiles of the filament. ne is the median electron density estimated from all profiles of the filament. Q0/area is the median of the EUV ionizing photon flux estimated from all profiles of the filament. Q0 is the median of the EUV ionizing photon rate estimated from all profiles of the filament. DCygOB2 is the approximate projected distance from Cyg OB2.
