Relation of the transition timescale (t_CL) with the black hole mass in logarithmic scale (log M_BH). The downward pointing purple arrows represent the upper limit of the transition time for all CL transitions in our study. The dashed-dot-dot-dashed blue, dot-dashed orange, dashed red, and solid green lines represent the viscous time, cold front propagation time, thermal time, and dynamic time, respectively. The timescales are calculated assuming a disk aspect ratio H/R = 0.2 and a viscosity parameter α = 0.1.
