Correlations between initial bar pattern speeds of Ω_p, init and its ratio with the final value Ω_p, final (top panel), the stellar-to-dark-mass ratio measured within the stellar half-mass radius M_*/M_DM(r <  r_h*) (second top panel), the maximum circular velocity V_c, max (second bottom panel), and the cold gas fraction f_gas (T <  10^4.5 K) also measured inside r <  r_h* (bottom panel). The values are averaged from six consecutive snapshots at the bar formation. The colour in the bottom panel marks the difference between the times when AGN-feedback prescription switched from thermal to kinetic and the bar formation times (or black crosses if this switch never occurred). In each panel, Spearman’s correlation coefficients ρ are provided.
