The main feature of this site is the reaction network. This is an active image, so it pays attention to the position of the mouse and to your mouse clicks. To use the image, find the part of it that interests you, point at it, click on it and you will see that part of the data. This applies both to the abundances of the elements and to the reactions converting one to another.
There are some things that are not easily part of the network. These are available in the table following the network image.
This organization is not friendly to non-graphical browsers (such as lynx), but since much of the information to be conveyed is pictoral, the concious decision to use a graphic interface was made. If you don't have one already, I strongly suggest a browser with graphic capabilities. I also suggest that images be loaded automatically on this site.
Some of the reaction lines in the network picture stand for more than one reaction mechanism. This was done primarily to reduce clutter on the picture and reduce image size. Also, since many of the reactions involve alpha particles, all of these have been given as originating at the other involved nucleus. This is to keep the helium 4 part of the image from being any more busy than it already is.
When clicking on the image, try to avoid the areas with overlap. Since the computer has no way of knowing which line you want when two overlap, it will give you the one I created a link for first. If this is the link you want, fine, but it can be confusing.
Lastly, a note about notation. The HTML 3.0 specifications include allowances for footnotes, margin notes, subscripts, superscripts and mathematical equations. Unfortunately, these are not entirely supported yet on any browser. Thus, we must make due with the resources that exist.
