MSX 8 μm image showing the spatial distribution of the O-type stars from Cygnus OB2 analyzed by Berlanas et al. (2020) (orange circles) and those identified in this work (pink triangles). The B0 population is plotted with squares in gray. For reference, the red star locates CygOB2 #8A, with J2016.0 coordinates RA = 20:33:15.078 and Dec = +41:18:50.479. The dashed circle defines a 1° radius region, centered on Galactic coordinates l = 79.8° and b = +0.8° (Knödlseder 2000). North is up, and east is to the left.
