Are these Mean Earth landing coordinates? Can we make room for Mare Orientale coordinates as well, or is it best to keep in one or the other (and prior consensus has been to use Mare Orientale coordinates)? We should probably have an article or two on coordinate systems... -- Strangelv 05:01, 15 January 2007 (PST)

Coordinates are given per the IAU standard. I do not recommend using different coordinate systems. Charles F. Radley 06:34, 15 January 2007 (PST)

This is the generally accepted standard which should be used:

IAU Mean Earth Polar Axis coordinate system, from the transformed Defense Mapping Agency 603 (DMA/603) lunar cartographic control network as described in Davies et al., J. Geophys. Res., v. 92, pp. 14177-14184, 1987.

The person who could best counterargue with you is Bryce Walden, who was one of the authors of a paper on what's wrong with the Mean Earth coordinate system, what it will take to replace it, and what is possibly the best system with which to replace it. I'd scrounge up the bookmark, but right now my files are spread across two machines, three partitions, and not a few things are not accounted for and may have been accidentally left behind when my previous notebook drive was wiped. -- Strangelv 07:44, 15 January 2007 (PST)
