I have now approximately removed the emission component from the spectrum of the central 6 arcsec region and divided it by the spectrum of the solar analogue to reveal the reflectance spectrum of this region independent of the solar spectrum.
It looks similar to some asteroid reflectance curves. Since the central region is so condensed and from the images there does not seem to be much dust, is it just scattering from dust particles of characteristic size or is it possibly representative of the comet nucleus albedo ?
