Velocity peak location v_p of o–H₂ 2.12 µm vs v_p [OI] 0.63 µm. Filled circles with error bars show the observed values; the black colour is for targets with v_p < 0 km s⁻¹ (i.e. blue-shifted wind component) for both the o–H₂ 2.12 µm and [OI] 0.63 µm; light-grey marks targets with v_p > 0 km s⁻¹ (i.e. no clear indication of a disk wind). The coloured symbols are for the models. Shown are models for the three different accretion luminosities and with a reduced dust-to-gas mass ratio in the wind (coloured diamonds). The size of the coloured symbols scales with the inclination; smallest symbols are for i = 0° largest are for i = 80°. The thick dashed line indicates v_pH₂ = v_p[OI] and the light grey stripe indicates v_pH₂ = v_p[OI] ± 3 km s⁻¹. Top panel: all data points; bottom panel: zoom-in (brown box) showing all the models and the observational data for targets with clear wind signatures, excluding DO Tau.
