If you want to go the second route that Ernie points out, then I suggest
that you use an Excel spread sheet called Physprops. It is done by Bradley
Hacker and can be found (or could be) on his web page. If you do this, I
strongly suggest that you also get the publication related to it from
G-cubed (it is probably on Hackers web page as well) which tells you how
everything works.
