cds-question@unistra.frstellar-associationso-starsmorgan-keenan-classificationThe Cygnus OB2 association and its surroundings display the richest collection of massive stars in our nearby Galactic environment and a wealth of signposts of the interaction between these stars and the interstellar gas. We perform a magnitude-limited, homogeneous census of O and early B-type stars with accurate spectral classifications in the blue, in a 6{deg}x4{deg} region centered on Cygnus OB2 that includes most of the Cygnus X complex, a sizeable fraction of the adjacent Cygnus OB9 association, and a large area of the field surrounding these complexes2012A&A...543A.101Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/543/A101CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/69 : MK, UBV Time and Latitude Stars (Sato+ 1990)J/AJ/101/1408 : Massive stars in Cyg OB2.
