Fig. 9
X-ray fluxes (FX) vs. magnitude in 2MASS J band (mJ). The solid line presents the relationship log (FX) = − 9.8( ± 0.4) − 0,33mJ similar to that obtained using ROSAT data in Paper I. The large symbols represent Herbig Ae/Be stars (M> 2M⊙). Dotted and dashed lines show 1σ and 2σ offset, respectively.
