I am trying to figure out what is the meaning of probability as applied to rendering of anisotropic ADP ellipsoids. I tried to read what's in the code, and it seems that the actual ellipsoid is uniformly stretched by
1.2*exp(0.3*(1/2-p)/(p*p-1)) where p is the corresponding probability. So, at 50% it is actually 20% bigger than the actual thermal ellipsoid? Ed. -- Coot verendus est
