Origin of n = 2 emission. We show geodesics corresponding to the maximum intensity of the n = 2 ring of each model along a horizontal cut, on the left (blue) and right (red) sides of the image (see inset of the upper-left panel). The accretion flow and spin parameters are specified in the upper-left corner of each panel. The blue and red ellipses encircle the region emitting most of the n = 2 photons loaded onto each geodesic. The blue geodesic is abruptly cut in the lower-right panel because the medium becomes optically too thick (defined in the code as a transmission smaller than 10−6). For each ellipse, the local values of the emitted frequency (νem), self-absorbed emission (em, in cgs units), transmission (tr), and redshift factor (g3) are provided, as well as the resulting increment of specific intensity δIν (see Eq. (13) for the definition of these quantities).
