(I haven't included the explanation of how the formula was derived; if you're interested, go to deja news and look up "re: Race wizard - Hab studies" by Bill Butler, 1998/04/10)
The full equation is:
Hab%=SQRT[(1-g)^2+(1-t)^2+(1-r)^2]*(1-x)*(1-y)*(1-z)/SQRT[3]
Where g,t,and r (standing for gravity, temperature, and radiation) are given by Clicks_from_center/Total_clicks_from_center_to_edge
and where x,y, and z are
x=g-1/2 for g>1/2 x=0 for g<1/2 y=t-1/2 for t>1/2 y=0 for t<1/2 z=r-1/2 for r>1/2 z=0 for r<1/2
The farther habs are from center, the less accurate the result of this equation will be. However, the errors are small, so the predicted answer will always be within a percentage or two of the actual value.
Thanks to Bill Butler for the mathematical wizardry.
