Reduced χ2 contours of the H2 2D and 1D line profile modeling for HD 97048 and HD 100546. For each star, the first three panels display the reduced χ2 contours for the 2D spectrum as a function of α and Rin for diverse values of Rout . The value of the minimum is indicated in the title. The contour in solid black is the contour of the minimum plus 0.1. Subsequent contours in gray dotted lines are at the minimum plus 0.5, 1, 3, 5, 10 in the case of HD 97048, and at the minimum plus 0.2 and 0.5 in the case of HD 100546. The rightmost panel shows the 1D line profile as a function of Rin for several values of Rout for a fixed α. For HD 97048 α = 1.5 is used, in the case of HD 100546 α = 1.0 is employed.
