32 pixel/degree equirectangular map produced using spacecraft position and image timing solution derived via photogrammetric optimization.

Photogrammetric control network consisted of 420 automatically selected match-points between datatakes.

Control network is strictly self-referential. No attempt was made to tie features to other maps or IAU nomenclature points.

No attempt has been made to mitigate illumination/view angle dependent brightness changes or camera internal reflections, other than application of a scale factor to produce roughly similar brightness between images.

Contrast is intended to be natural-ish.

Control point network creation and parameter optimization software implemented in Mathematica.

Uses NASA's Navigation and Ancillary Information Facility SPICE toolkit software.
