Fractional X-ray luminosity vs. Rossby number for h Per members. The light blue solid line indicates the saturated and non-saturated relation obtained for MS stars by Wright et al. (2011). Black symbols mark h Per members used to perform the best fit in the expected non-saturation regime (i.e., Ro> 0.04 and M> 1.0 M), with the red dashed line being the best-fit relation. Gray symbols indicate the remaining h Per members.
