UV excess luminosity measurements obtained in this study are compared to Rebull et al. (2002)’s for objects in common to both samples (Rebull, priv. comm.). On the x-axis, dots correspond to the median detected during the 2 week-long CFHT monitoring, while variability bars depict the actual range in values measured at different observing epochs during the survey. The equality line is traced as a solid line to guide the eye.
