Leading edge ratio leratio (left panel) and scale length ratio rdratio (right panel), respectively, as a function of the projected infall-angle ϕ for blue cloud (blue squares, solid line) and dusty red galaxies (red circles, dashed line). Left panel: the leading edge ratio decreases as the infall becomes more edge-on. Right panel: the scale length ratio declines for a more face-on infall (binsize: blue clouds = 15, dusty reds = 10).
