That's where you lose me. I only want to see if there are any anomalies within the time/data sets that I record. According to the data already gathered by Devereux, Mereaux, Burke and Halberg, the z-axis appears the most pertinent where megaliths are concerned, so this is what I intend to monitor.Coal wrote: You're going to get into the interaction of three-dimensional vector fields and that was pretty hard maths (at least it was for me some 25 years back).
