Map-projected example images of M³ targeted and global data used in this study. Figure letter colors correspond to image strip colors in Figure 1. (a) M³ global data of the study region, optical period 1b (morning), image M3G20090212T103632 (140 m pixel⁻¹). (b) M³ targeted data of the lunar highlands study region, optical period 2a (afternoon), image m3t20090421t183929 (70 m pixel⁻¹). (c) Subset (100 m pixel⁻¹) of the M³ image in (a). Five study region sites from which spectra were acquired are labeled in (c). Box colors correspond to Figure 4 colors. North is up in all images. Crater diameters are as follows: site 1: Bunsen A (∼41 km), site 2: Gerard B (∼14 km), site 3: Galvani D (∼9 km), site 4 and site 5: McLaughlin D (∼11 km).
