Log Q with respect of parameter , spectroscopic representative of the luminosity, for the O standard stars. Upper and lower limits are represented by arrows. Different colors and shapes represent luminosity classes. Open symbols indicate stars for which we have detected clear or likely signatures of spectroscopic binarity. The solid line represents the linear regression of the values, excluding stars marked with an open symbol and/or an arrow.
