class HParticleVertexFind: public HReconstructor

_HADES_CLASS_DESCRIPTION

 HParticleVertexFind

   Vertex finder using weighted LSM with optional Tukey weights

 To use it in a macro just add

 taskset->add(new HParticleVertexFind("name","title",tukey)

 where  input data is read from HParticleCand (r,z,phi,theta from RK)
 Only candidate flagged kIsUsed are taken into account . Inner segment
 is require to be fitted and RK chi2 < 1000. Candidates markes as fakes
 are skipped by default.

 As for 'tukey' it can be kTRUE or kFALSE depending on if Tukey weights
 should be used in the minimization. For low multiplicity environments
 like C+C I would recomend kFALSE; at least until I have found better
 parameters for the Tukey weigths minimization.
