Descripción
The Cygnus OB2 association contains some of the most massive and most luminous O-stars in the northern hemisphere. As a first step toward studying the initial mass function of Cyg OB2, uvby and JHKL-prime photometry were obtained for about 80 OB candidates in the region. The c1 vs. (b-y) color-color diagram is shown, indicating the main sequence line, approximate types, and reddening line. These results are briefly discussed.
