Notes. The parameter that was changed from the fiducial model is highlighted in bold. For each superoutburst, we measured the outburst duration in days, the delay from the start of the outburst until the appearance of superhumps in days, the maximal disk eccentricity, aspect ratio, visual magnitude, superhump magnitude, and superhump excess. We list the mean of the measurements if multiple superoutbursts occurred in a simulation. The superhump delay is measured from the first torque maxima during the precursor to the second torque maxima during the eccentricity growth phase, compare Fig. 15.
