Class Description

{ }
RooEllipse(const char *name, Double_t x1, Double_t x2, Double_t s1, Double_t s2, Double_t rho, Int_t points)
 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 printToStream(ostream& os, PrintOption opt, TString indent)
 Print info about this histogram to the specified output stream.

   Standard: number of entries
    Verbose: print points on curve
void Print(Option_t *options= 0)
Double_t getFitRangeNEvt()
 These methods return zero to indicate that they do not support
 this interface. See RooPlot::updateFitRangeNorm() for details.
{ return 0; }
Double_t getFitRangeNEvt(Double_t, Double_t)
{ return 0; }
Double_t getFitRangeBinW()
{ return 0; }
