Secondly, the grouping of stain images is very intriguing, clustered almost 180 degrees apart. Though there are only a little over 100 stain images, these were collected randomly throughout the MOC image folders and were mixed in among thousands of other images, so the statistical sampling if it shows any relationships, is significant. There are many many non-stain images that fall above 40 degrees north and 40 degrees south, I'm just plotting the equatorial zones as a comparison. There is still much study to be done. As well I am getting elevation data for the stains using the MOLA mapping.
More data gathering is needed before any firm conclusions can be made.
These maps and extrapolations are fairly rough but close enough to give a general idea. However I do see a trend in this information and a string is begging to be pulled. My purpose here is to get more attention into this phenomenon. NASA with it's much vaster resources and data at hand can easily verify what I am doing and which I am just scratching the surface of. I don't want to make any wild assumptions, but some of these correlation's are easy enough to see and require further study.
