Bolometric luminosities vs. maximum wind velocity for the objects in Fiore et al. (2017) (red crosses: molecular and ionised winds; blue squares: warm absorbers; green downwards triangles: UFOs; orange stars: BALs) for WISSH BI > 0 BAL QSOs (purple stars for the 21 C IV BALs), and for C IV winds from Vietri et al. (2018; cyan upwards triangles). The region occupied by the G09 objects with BI > 0 is shown in faded grey (the artificial v_max boundaries are a consequence of the BI selection).
