But there also seems to be a basic inconsistency between all the values. First, until recently, we did not have a very accurate cartographic control network for the Moon. Thus, your coordinate knowledge is only as good as the global control network you are using. Moreover, to make this even more confusing, the flight people at the Houston mission control and the lunar map makers used different control networks, and those networks were constantly being modified during the Apollo flight program, as our knowledge improved, so many different numbers found their way into print. The second reason the numbers don't agree is much easier to understand.
People are often both lazy and ill-informed.
Thus, in case more than one set of numbers exists, the different sets or even mixtures between them may become current. I have no doubt that different numbers will continue to be quoted for the foreseeable future, as apparently no one can be bothered to do the work needed to reconcile all of them. 92, number B13, pages 14177 to 14184. The authors are Merton Davies et al. Merton Davies is a very reliable source, so I'm glad to have that reference.
