I wonder whether there's been any serious research in this area.  Sure seems that it's a fairly important part of science.  I suspect the military would be very interested in all things
to do with propagation, especially in years past.  I would imagine that they'd run across the differences if they were looking....whether they'd care or not, I'm not sure, but things like this
should be published somewhere, wouldn't you think?  .......Walt.
