# (U)C HII + L>10$^4$ L$_\odot$ YSO sample — d < 3 kpc

**N = 102**  (HII ~58, YSO ~44, incl. 2 marginal)  
Best literature distances; L rescaled to best distance. Sorted by Galactic longitude.  
Sources: RMS (Lumsden+2013) + ext literature search + curated non-RMS (Orion/NGC6334/etc, off-plane or |l|<10 GC-excluded). Off-plane & on-plane IRAS/Akari completeness checked.
