Results of the gravitational torques (weighted with the molecular gas distribution), angular momentum transfer, and resulting gas flow, both in radial bins and integrated out to radius R for our ICA dust-corrected stellar mass map (solid black line) and the original 3.6 μm image (dashed blue line). Positive values imply radial gas outflow, negative values denote an inflow. The innermost bin has been shaded to emphasise that it is subject to high uncertainties.
