Notes. ( * )Radio Master catalogue is a combination of two previous catalogues from Dixon (1970) and Kühr et al. (1979). ( * *)Galactic O star Catalogue was taken from Maíz-Apellániz et al. (2004). ( * * * )Simbad Database catalogue was constructed using a VO search with a radius of 24 arcminutes, centred on the Cyg OB2 association. ( † )Each of these catalogues was derived from its respective large-scale survey using the NASA/IPAC Infrared Science Archive. The number of sources represent those within a 24 arcminute radius of the centre of the Cyg OB2 association.
