Effect of using different minimum radii r_min on the gamma-ray spectra. The solid and dashed lines represent analogous cases using r_min = 10 R_g and r_min = 6 r_eq, respectively. Panels a and b show the cases where n = 1, ${\hat{l}}_{c} = 3$ $\hat{l}_c=3$ and n = 0.9, ${\hat{l}}_{c} = 3$ $\hat{l}_c=3$ , respectively. In both panels we consider m = 0 (blue lines) and m = 0.2 (green lines).
