Phase curves of three regions around the Apollo 15 S-IVB impact derived from 49 LROC NAC pairs with a corresponding map showing the sampling locations. The phase curve illustrates that the distal ejecta have a higher reflectance than the background regolith at lower phase angles (<20°), but this trend reverses at higher phase angles (>60°).
