Detailed Description

template<typename charge_t>
class Acts::SingleCurvilinearTrackParameters< charge_t >

Curvilinear track parameters for a single track.

Template Parameters

charge_t Helper type to interpret the particle charge/momentum

This is intended as a user-facing data class that adds additional accessors and charge/momentum interpretation on top of the pure parameters vector. All parameters and their corresponding covariance matrix are stored in curvilinear parametrization.
