Constructor & Destructor Documentation

JKatoomba()

JACOUSTICS::JKatoomba< JAbstractMinimiser >::JKatoomba ( const JGeometry & geometry, const JSoundVelocity & velocity, const int option )

inline

Constructor The option corresponds to the use of fit parameters in the model of the detector geometry.

A negative implies that all strings in the detector use common fit parameters.

Parameters

geometry	detector geometry
velocity	sound velocity
option	option
