Notes. Top headers: Pr/Pavg, the relative excess of the polarisation degree with regard to the average value at the given phase angle (α); FSi/Fcont, the relative excess of the 10 μm silicate emission feature to the local continuum. LPC, NPC, HTC, and JFC are the abbreviations of long-period comets, non-period comets, Halley-type comets, and Jupiter-family comets, respectively. ( † )Right after the Deep Impact experiment.
