  HMetaMatchPar

  Parameter container for HMetaMatchF

 Rich:
   Tr - angle theta of ring from HRichHit (in degree) in lab.coor.sys.
   Pr - angle phi of ring from HRichHit (in degree) in lab.coor.sys.
   Tm - angle theta of ring from HRichHit (in degree) in lab.coor.sys.
   Pm - angle phi of ring from HRichHit (in degree) in lab.coor.sys.
   SigmaTheta= (richThetaMaxCut - richThetaMinCut)/2.
   Toffset   = (richThetaMinCut + richThetaMaxCut)/2.
   qualityRich =
     sqrt[((Pr - Pm - richSigmaPhiOffset)*sin(Tm)/richSigmaPhi)^2 +

     "richSigmaPhi" (sigma of this distr.).
     Select "richQualityCut", for example 1.0.

  RichIPU:

   Tm - angle theta of ring from HRichHitIPU (in degree) in lab.coor.sys.
   Pm - angle phi of ring from HRichHitIPU (in degree) in lab.coor.sys.
   SigmaTheta= (richIPUThetaMaxCut - richIPUThetaMinCut)/2.
   Toffset   = (richIPUThetaMinCut + richIPUThetaMaxCut)/2.

     example) "richIPUSigmaPhiOffset" (mean of this distr.).
     From distribution of (Pr-Pm-richIPUSigmaPhiOffset)*sin(Tm) to get
     "richIPUSigmaPhi" (sigma of this distr.).
     Select "richIPUQualityCut", for example 1.0

   dXs,dYs - hit position errors (== HShowerHit::getSigmaX(), getSigmaY())
   Xm,Ym - mdc segment cross point with shower module in coordinate system
           of corresponding shower module
   qualityShower =
     sqrt[((Xs - Xm - showerSigmaXOffset)/sqrt(dXs^2 + showerSigmaXMdc^2))^2 +

     (mean of this distr.).
     From distribution of (Xs-Xm-showerSigmaXOffset)/dXs (!) to get
     sigma of this distribution.
     If sigma > 1. to calculate "showerSigmaXMdc" = sqrt(sigma^2 - 1.),
     otherwise set "showerSigmaXMdc" = 0.
     From distribution of (Ys-Ym) to get "showerSigmaYOffset".
