Kieran,

The list recently had a series of postings by Jan Kalivoda discussing
rigorous vs. approximate methods. You may already have seen them and are
now after something more specific.  If you haven't seen them, they are a
right on your topic.  After several responses to the initial article, a
revised version was posted incorporating various minor clarifications.
This final posting is available at
http://www.i-DEADLINK-com/lists/navigation/0304/0048.html.  If you wish to
read the entire thread from the beginning, start at
http://www.i-DEADLINK-com/lists/navigation/0304/0022.html. These links are
also available at the Nav-L section of www.LD-DEADLINK-com.

I hope you will share your paper with the list, good luck with it.

Regards,
Arthur

Subject: Re: Rigorous v Approximate methods

I am attempting to write a paper on historical navigation methods using
Lunar Distances and have come across numerous examples of sight
reduction
using a rigorous method as outlined in both Norie and Raper. However
they do
not say what is rigorous about the method and how it compares to the
approximate methods also mentioned in both texts.

I presume the texts are referring to solutions of the spherical
triangles in
the Lunar Distance reduction process but I am lost.

Can someone direct me to material which explains the difference?

Also I am trying to use graphical symbols in my paper sun as sun ll,
moon ll
but cannot find them in any program. Does anyone on the list have a set
of
symbols which I could use for incorporation in documents in a format
compatible with a program such as photoshop.
