Notes.
Complex refractive indices obtained from Dorschner et al. (1995).
Central wavelength of the SPHERE/IRDIS H3 filter which is sensitive to methane absorption. For the other models, we used the central wavelength of the SPHERE/IRDIS H2 continuum filter, λ = 1.59μm.
Irregularly shaped particle properties are approximated with a distribution on hollow spheres (DHS; Min et al. 2005).
