Well Michael, I was really referring to all of the comments. They are right on, but unanswerable for the most part due to the redacted text we are presented with. I may have actually read the report or read Grant's original of that text, but it was about 1970 or so.

I doubt that there is any equipment at GEH to do the work you are considering. If I find any I'll let you know. Holmburgers is on his way home today to be with family over the holidays. I can ask him when he gets back.

I have heard that there may be some equipment around Rochester somewhere. I've never bothered to contact anyone to follow up. After all, it is a labor intensive job doing the readings and then the plots from the raw data.
