Outflow mass rates as a function of L_bol for the full SUPER sample. Upper and lower panels show our trust Ṁ_out values and Ṁ_max mass rates, derived using v_max in Eq. 2. Triangles indicate lower limits to mass rates. In the lower panel, scaling relations from Fiore et al. (2017) and Musiimenta et al. (2023) are shown as dotted and dashed lines, after being re-scaled to n_e = 500 adopted for our targets, while values of Ṁ_max have been multiplied by a factor of 2 to match definitions adopted in Fiore et al. (2017) and Musiimenta et al. (2023). Compared to Fig. 8, the distribution of measurements is more scattered, with no clear discrepancy between the type-1 and type-2 samples. The comparison is furthermore hampered by the large number of lower limits to mass rates.
