Halo fit for all filters with logarithmic ordinates. The fluxes are normalized to the total flux. Left panel: halo fit from the radial profile of images in the two filters for RS Pup. Right panel: halo fit from the radial profile of images in the two filters for Achernar. The fit in IB_2.18 was for r > 0.26″ and in NB_1.64 for r > 0.2″ for RS Pup and for r > 0.26″ for Achernar. The dashed lines denote the reference stars, while the thick lines denote the Cepheid and Achernar. The fitted curves are plotted in gray.
