The method string used in {{{rave::VertexFactory}}} has the following general structure:

{{{
finder-name:value-name:value-...
}}}

Sometimes nesting is required (e.g. to configure "sub-algorithms"):

{{{
finder-name:value-name:(value-name:value-name:value)....
}}}


As for the finders, the following algorithms are defined:

 * '''kalman'''
   KalmanVertexFitter This is the simple linear kalman filter that takes no extra parameters. 
 * '''avf'''
   AdaptiveVertexFitter The avf respects the following parameters:
   * ''sigmacut'': The value for [ = sqrt (2) ] at which a track has track weight=0.5. 
   * ''Tini'': Initial temperature in the annealing schedule. 
   * ''ratio'': The ratio with which the temperature falls in each iteration step. 

   Default is: avf-Tini:256-ratio:0.25-sigmacut:3 
 * '''tkf'''
   TrimmedKalmanVertexFinder The tkf respects the following parameters:
   * ''ptcut'': Cut in the tracks' pT, given in GeV/c. 
   * ''vtxcut'': Bla FIXME 
   * ''trackcutpv'': Bla FIXME 
   * ''trackcutsv'': Bla FIXME 
   
   Default is: tkf-ptcut:0-trkcutpv:0.05-trkcutsv:0.01-vtxcut:0.01 
 * '''mvf'''
   MultiVertexFitter:
   * ''sigmacut''

   Default: mvf-sigmacut:9.0
 * '''avr'''
   AdaptiveVertexReconstructor: Iterative adaptive vertex fitting.
   * ''primcut'': Cut (in terms of sigma) on the primary (i.e. first) vertex
   * ''seccut'': Cut (in terms of sigma) on all subsequent vertices)
   * ''minweight'': Minimum track weight to be used in subsequent avf fits.

   Default is: avr-minweight:0.5-primcut:2-seccut:6
