Correlation between the observed and modelled scattered light in the J, H, K_S, and 3.4 μm bands. The model results correspond to models where the densities have been scaled down to match the NICER extinction measurements (J13 dust, and W = 1). The data have a resolution of 25′′ resolution and sample at 7′′ steps the areas marked in Fig. 8f. The blue points correspond to the larger area and the red points to the smaller area. The dashed lines show robust least squares fits to the red points. The values of the slopes and correlation coefficients r are given in the frames.
