Fig 10. Assessing the dependence of f_res and Q_Z of the intermediate ${\overline{g}}_{Ca}$ models on the linear ${\overline{g}}_{Ca}-{\overline{g}}_H$ correlation.

a. Parameter values for each model were in the intermediate ${\overline{g}}_{Ca}$ group (see Fig 7) were changed along a line parallel (‖, blue) to the correlation line (black) or along a perpendicular line (┴, grey). For each model and each line, ‖ or ┴, we fit a line to the relative change in either f_res or Q_Z as a function of the relative change in ${\overline{g}}_{Ca}$. b. The sensitivity values of f_res or Q_Z to ‖ or ┴ are shown for the three groups. c. Impedance profiles showing how Q_Z changes when the parameters vary along a line parallel (blue) or perpendicular (grey) to the ${\overline{g}}_{Ca}-{\overline{g}}_H$ correlation line in one optimal model. Arrows show the direction of the movement of Z_max and f_res for the change in parameters along ‖ or ┴.
