Definition at line 608 of file JFitK40.hh.

Constructor & Destructor Documentation

◆ JK40Parameters()

JCALIBRATE::JK40Parameters::JK40Parameters ( )

Member Function Documentation

◆ getInstance()

static const JK40Parameters& JCALIBRATE::JK40Parameters::getInstance ( )

inlinestatic

Get default values.

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.

Returns: parameters
