GENFIT - a Generic Track-Fitting Toolkit

Understand

GENFIT is an experiment-independent track-fitting toolkit that combines fitting algorithms, track representations, and measurement geometries into a modular framework.

• We report on a significantly improved version of GENFIT, based on experience gained in the Belle II, PANDA, and FOPI experiments.
• Improvements concern the implementation of additional track-fitting algorithms, enhanced implementations of Kalman fitters, enhanced visualization capabilities, and additional implementations of measurement types suited for various kinds of tracking detectors.
• The data model has been revised, allowing for efficient track merging, smoothing, residual calculation, alignment, and storage.
