Hertzsprung-Russell diagrams for 175 A and F stars in the young clusters Coma, Alpha Persei, Praesepe and the Pleiades are investigated to determine the accuracy of binary identification on the basis of where the main sequence is drawn. It is found that a main sequence fitted to rotating single stars conceals some binaries and gives others artificially low mass ratios; on the other hand, a main sequence fitted to nonrotating single stars makes the rotating ones appear binaries. Thus without data in addition to the Hertzsprung-Russell diagrams, no conclusion can be drawn as to whether open cluster stars and field stars differ in binary frequency or distribution of mass ratios.
