Detailed Description

Interface class for vertex fitting AlgTools, for more detailed information, take a look at the header file of the actual implementation file.

In general, the vertex fitters is an AlgTool, taking a list of tracks or their parameters as an argument and returning a vertex candidate.


Modification for the use of VertexSeedFinders (algorithms providing initial point of linearization); February 2006
