Evolution of the Henyey-Greenstein g coefficient with wavelength. It is based on the values derived by Debes et al. (2008) and Schneider et al. (2009) for the HST images, using scattering angles between 5° and 15° from the major axis, and on our results for the VLT/NaCo new reduction at L′ (Sect. 4.2.2).
