Handles propagation and material effects.

extrapolateToPlane(), extrapolateToPoint() and extrapolateToLine() etc. call this function. Extrap() needs a plane as an argument, hence extrapolateToPoint() and extrapolateToLine() create virtual detector planes. In this function, RKutta() is called and the resulting points and point paths are filtered so that the direction doesn't change and tiny steps are filtered out. After the propagation the material effects are called via the MaterialEffects singleton. Extrap() will loop until the plane is reached, unless the propagation fails or the maximum number of iterations is exceeded.

Extrapolates the state to the POCA to a point in the metric of G, and returns the extrapolation length and, via reference, the extrapolated state.

If stopAtBoundary is true, the extrapolation stops as soon as a material boundary is encountered.

If state has a covariance, jacobian and noise matrices will be calculated and the covariance will be propagated. If state has no covariance, jacobian and noise will only be calculated if calcJacobianNoise == true.

propagate state7 with step S. Fills SA (Start directions derivatives dA/S). This is a single Runge-Kutta step. If jacobian is nullptr, only the state is propagated, otherwise also the 7x7 jacobian is calculated. If varField is false, the magnetic field will only be evaluated at the starting position. The return value is an estimation on how good the extrapolation is, and it is usually fine if it is > 1. It gives a suggestion how you must scale S so that the quality will be sufficient.

Propagates the particle through the magnetic field.

If the propagation is successful and the plane is reached, the function returns true. Propagated state and the jacobian of the extrapolation are written to state7 and jacobianT. The jacobian is only calculated if jacobianT != nullptr. In the main loop of the Runge Kutta algorithm, the estimateStep() is called and may reduce the estimated stepsize so that a maximum momentum loss will not be exceeded, and stop at material boundaries. If this is the case, RKutta() will only propagate the reduced distance and then return. This is to ensure that material effects, which are calculated after the propagation, are taken into account properly.
