Radial (top two panels) and vertical (bottom) opacity profiles in equilibrium disks which we use to study the torque dependence on the opacity gradients. In the top panels, the individualcases are distinguished by colour and labelled in the legend. The profile of the κ_BL -disk (solid grey curve) is plotted for comparison. The bottom panel corresponds to the protoplanet location and demonstrates that only thedisks with T-dependent opacities develop a vertical opacity gradient (which is not allowed for r-dependent opacities by construction).
