Statistical constraints on the shape of the local matter density profile at the present time. LTB models with fixed radial size L = 3Gpc and three equidistant interpolation nodes were constrained by measurements of the local Hubble rate and supernovae. The blue error bars and the grey-shaded band indicate the 68% confidence intervals for the cubic spline and linear interpolation schemes, respectively. The black dashed line connects the means of the best-fitting nodes for the linear interpolation scheme. The green solid curve shows the best-fitting cubic spline density profile.
