a B-scan over Mare Imbrium at the selenographic longitude of 345.3 E°. The origin of the apparent depth is taken at the Moon’s surface assuming the averaged radius of the Moon to be 1737.4 km. b Another B-scan image at the selenographic longitude of 345.0 E°. Several strong echoes of parabolic shape are due to craters nearby. c Taking running means highlighted the subsurface reflectors especially for those starting from the horizontal black arrows, which continue to ~ 42 N°
