Re: HO 211 Umland version

From Paul Hirose:

I finally took a good look at the version of the HO 211 sight
reduction table that Chuck Griffiths pointed out for us. Its creator,
Henning Umland, has made the table available for download on the Web.

http://home.t-online.de/home/h.umland/index.htm

Some of his table's features are arguable. In my opinion there are an
excessive number of significant digits. For example, in the A column,
from zero to 50 degrees, there's at least one more significant digit
than needed for interpolation to .1 minute...

Well, I'm glad someone else found it worth looking at. I was interested to hear
that Mr. Umland wasn't the first to attempt this approach.
