(a) LRO WAC mosaic (Speyerer et al. 2011) of the crater Pierazzo and surroundings. The yellow box outlines the region considered for obtaining the Fe abundances using different approaches. (b) Full resolution M³ mosaic of the region east of the crater Pierazzo. (c)–(f) Fe abundance derived using four different methods. The algorithm of Lucey et al. (2000b) was applied to Clementine UV/VIS data at 100 m/pixel spatial resolution. The prominent ray structures are visible in the Fe abundance maps derived using the algorithms of Bhatt et al. (2015) and Wöhler et al. (2014) but are indistinguishable from the surroundingsurface in the Fe abundance map derived using the proposed MLR approach considering LP GRS as a reference.
