Table 3

Geometric albedo Ag, phase integral As/Ag, and quadrature results for the planet Earth.

B V R I
A g 0.504 0.3671 0.320 0.301
As/Ag 0.86 0.86 0.86 0.86
values for α = 90°
pE [%] 24.6 19.1 13.5 8.3
ΔpE [%] ± 1.2 ± 1.3 ± 0.9 ± 1.4
f E 0.136 0.099 0.086 0.081
pE × fE [10-3] 33.41 18.90 11.66 6.73
Cp [10-11] 6.07 3.44 2.12 1.22

Notes. Given are the fractional polarization pE, the Earth reflectivity fE,the polarized reflectivity pE × fE, and the polarization contrast for an Earth-Sun system. The systematic offset uncertainty ΔpE is due to the uncertainty of the depolarization and albedo of the lunar surface.
