Fig. 15From: Estimation of bulk permittivity of the Moon’s surface using Lunar Radar Sounder on-board Selenological and Engineering ExplorerEstimates of ε1 (red), ε2 (blue) and εgrain of Mare Crisium for a 10–15°N and b 15–20°N. The regional representatives of εgrain = 6.17 (for 10–15°N) and 6.29 (for 15–20°N) are shown by horizontal green lines. The vertical error bars for ε1 and ε2 show 95% confidence intervals, while horizontal error bars denote their spatial extentBack to article page
