Photometric behavior of NIR band depths in small bodies explored by space missions.

Body	Albedo	Band depth vs. phase^(*)	Reference
Vesta	0.40	Increasing	Longobardo et al. (2014)
Ceres	0.09	Increasing	Longobardo et al. (2019)
67P/Churyumov-Gerasimenko	0.06	Constant	Longobardo et al. (2017)
Ryugu	0.04	Decreasing	This work

Notes. ^(*)The band depths considered include 0.9 and 1.9 µm for Vesta (due to pyroxenes), 2.7 and 3.1 µm for Ceres (due to ammoniated phyllosilicates), 3.2 µm for 67P/Churyumov-Gerasimenko (due to organics and ammonium salts), and 2.7 and 2.8 µm for Ryugu (due to phyllosilicates).
