This sub-solar longitude mosaic is composed of images with consistent lighting geometries (sub-solar longitudes from 200 to 229) selected to optimize illuminated terrain coverage over an Artemis III candidate landing site. For a first pass at offset correction, we used the results of aligning most of the LROC NAC images poleward of 84°S as described in Wagner et al. 2022 (LPSC LIII, Abstract no. 2573). For our second pass at offset correction, we compared the mosaic to the LOLA shaded relief product (5 m pixel scale). We estimate the absolute positional accuracy to be 5 to 20 m.

PDS PRODUCT NAMING CONVENTION
The PRODUCT_ID naming convention for LROC NAC ROIs is:
NAC_ROI_xxxxxxxxSSv_AyyyBzzzz[_##M].IMG where
Example: NAC_ROI_APOLLO15LOC_E252N0018.IMG is a NAC ROI of the Apollo 15 landing site with low-Sun. C indicates it's the third low-Sun mosaic of the Apollo 15 landing site produced. This mosaic is centered at latitude=25.2N, longitude=1.8E and is in equirectangular projection.
