Constructor & Destructor Documentation

◆ RooEllipse() [1/2]

RooEllipse::RooEllipse ( )

Default constructor.

Definition at line 47 of file RooEllipse.cxx.

◆ RooEllipse() [2/2]

RooEllipse::RooEllipse ( const char *  name,
Double_t  x1,
Double_t  x2,
Double_t  s1,
Double_t  s2,
Double_t  rho = 0,
Int_t  points = 100 
)

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.
