Residual between the fitted and simulated azimuthal anisotropy as a function of the disk inclination. The filled symbols represent the radially averaged anisotropy difference and the colored area indicates the corresponding standard deviation. For easy comparison between the various cases, the dashed lines in panels B, C, D and E delineate the colored area of panels A, B, C, D, respectively, while the dotted lines in panels B, C, D and E represent the values (symbols) of panels A, B, C, D, respectively.
