Map of the (top) phase ratio I(5°)/I(15°) at 2.0 μm and (bottom) phase reddening (with spectral slope computed between 2.1 μm and 2.5 μm). The maps were computed using a 10° × 10° grid at the Ryugu surface. The particularly high phase ratio and low phase reddening values for some grid elements located at latitudes above 10°N are due to a narrower phase angle range (see Appendix F, Figure F3). All grid elements above this latitude were discarded for the computation of the average east and west properties.
