Constructor & Destructor Documentation

◆ JFitK40Parameters() [1/2]

JCALIBRATE::JFitK40Parameters::JFitK40Parameters ( )

inline

Default constructor.

The default parameter values are set to those obtained from a designated simulation of K40 decays (see http://wiki.km3net.de/index.php/OMGsim_simulations_for_K40_fit).
If you change these values, you may also want to change the corresponding values in JK40DefaultSimulator.hh.
