Notes. The two-component model treats disc and ring contributions separately, whereas the single-component model “system” represents the mean temperature of the ring-disc system. Treating the band-average results listed in Table 4 as individual measurements of four Saturn observational seasons, the two- and single-component models have two and three degrees of freedom (d.o.f.), respectively.
