Newer Kinematic Fitting Documentation and Examples (Will Levine, March 2012)
The stuff below is somewhat outdated and the examples don't compile. I tried to write some brief updated documentation and an example
Brief Kinematic Fitting Example
Older Kinematic Fitting Documentation and Examples (Matt Bellis, 2007-2009)
- GlueX-doc-905 Kinematic Fitting Talk
- GlueX-doc-1381 Kinematic Fitting Talk
- Software to demonstrate how to use the kinematic fit:
- Example programs exist in the subversion repository here: https://halldsvn.jlab.org/repos/trunk/sim-recon/src/programs/Analysis/Examples/KinematicFitting
- If you have checked out the src tree then just look in the $HALLD_HOME/src/programs/Analysis/Examples/KinematicFitting directory
- Here is the original message posted with the initial version of the example code:
