Separation evolution for the two merging disc galaxies setup M1q0.5fg0.1 without (left panel) and with (right panel) MBH accretion and feedback at 100, 50, and 10 pc resolutions. Ten runs are shown for each resolution with different initial star formation locations for the purpose of assessing the influence of small stochastic effects. The vertical dotted lines indicate when the MBHB evolution is handed over to RAMCOAL from RAMSES at the boundary of the resolution sphere. One additional run with resolution-dependent AGN feedback efficiency at each resolution is also plotted to illustrate the effect of feedback efficiency on the results.
