a Comparison of Fano-formula with the scattering profiles of the oligomers. The brown and magenta dotted (vertical) lines represent, respectively, the spectral positions of the Fano peak and the Fano dip used to calculate the q-parameter; b Effect of a on the q-parameter when d = 15 nm and h = 40 nm; c Effect of d on the q-parameter when a = 80 nm (in quadrumer) and 60 nm (in heptamer) and h = 40 nm; d Effect of h on the q-parameter when a = 80 nm (in quadrumer) and 60 nm (in heptamer) and d = 15 nm
