a-b, Reduced χ2 from the coarse grids of the three free parameters: α, Rin and Rout. In each panel, the reduced χ2 for each pair of two parameters is lowest one by setting the remaining parameter free. c, Reduced χ2 from the fine grid of α and Rin with Rout=61 AU. In each panel, the pentagram symbol marks the minimum reduced χ2.
