Function documentation

 Default constructor
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.
void printName(ostream& os) const
 Print name of ellipse on ostream
void printTitle(ostream& os) const
 Print title of ellipse on ostream
void printClassName(ostream& os) const
 Print class name of ellipse on ostream
void printMultiline(ostream& os, Int_t contents, Bool_t verbose = kFALSE, TString indent = "") const
 Print detailed multi line information on ellipse on ostreamx
void Print(Option_t* options = 0) const
 Printing interface
