For additional information on and analysis of this map, please see preprint of Warell and Limaye (2001) paper in Plan. Space Science.
The spherical maps are presented with and without a white longitude/latitude grid for longitudes 0 to 360 and latitudes -60 to 60 at 30 degree increments. The sub-earth longitude, latitude and the sub-solar longitude is given for each image. Celestial north is up, celestial west is to the right and Mercurian longitudes are increasing towards Mercurian west (left).
The sub-earth point is marked with a cross. The sub-solar point is marked with a short vertical line on the equator (Mercury's obliquity is negligible) and will fall on the invisible hemisphere for disks which are less than half illuminated from an Earth-based perspective (i.e., if the sub-earth point will fall on the unilluminated hemisphere).
No attempt has been made to generate disks with correct relative sizes. In case of questions or for requesting synthetic Mercury disk maps, contact Johan Warell.
