re: #191 Walter L. Newton

No, that’s the point. Since 1850, different physical locations depending on which agency they got the information from, and this changed over the years, and there are a lot of times they had not data and then there is about 2 percent data that they can’t even account for.

And they can’t tell you now which agency, which location for each entry.

So the entry used for each cell at each particular time is based on a single reading?
