This agrees with observation: facular emissivity is initially indistinguishable from that of the photosphere at disk center.
dagger]) The fifth Planckian proof, as related to facular emissivity, was initially presented as the 15th line of evidence [45].
In addition, as facular material is tightly associated with sunspots and may well have been ejected from such regions, it was not unreasonable to extrapolate that their increased metallicity occurs as a result of assuming a Type-II lattice, despite the fact that they appear to float on the photospheric surface [20].
