The method string used in rave::Factory 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
