	Ok that's fair. Not being an astronomer, I just  picked the
equations out of a book and stuck them into code. The point is that once
you
have luminosity you can calculate mass to a fair degree of accuracy (I
mean
they are only estimates in the first place). Again looking at the code
most
of the details rely on having a luminosity value to generate them. So
whether luminosity is the defining factor for these values or whether
they
are just proportionally related it doesn't matter too much.

	btw. The book I worked from was Kauffman's "Universe".

	PS: Anyone know how to determine the colour of a star in RGB
form
given its luminosity ? I had to guess and something a little closer to
reality would be nice.
