Difference in axis ratio q and position angle ϕ_q between mass and light. Left: principal values of axis ratio q for mass and light maps of our galaxy sample, with both histograms added in the panel to the right. The magenta dashed line means y = x. Right: difference of averaged ϕ_q and q (within two annuli) between mass and light maps for our sample. Dashed lines indicate 16%, 50%, and 84% quartiles.
