Create a 2-dimensional ellipse centered at (x1,x2) that represents the confidence level contour for a measurement with errors (s1,s2) and correlation coefficient rho.
The resulting curve is defined as the unique ellipse that passes through these points:
(x1+rho*s1,x2+s2) , (x1-rho*s1,x2-s2) , (x1+s1,x2+rho*s2) , (x1-s1,x2-rho*s2)
and is described by the implicit equation:
x*x 2*rho*x*y y*y --— - ------— + --— = 1 - rho*rho s1*s1 s1*s2 s2*s2
The input parameters s1,s2 must be > 0 and also |rho| <= 1. The degenerate case |rho|=1 corresponds to a straight line and is handled as a special case.
