Detailed Description

Algorithm which refits Acts tracks using the ACTS GSF.

Input: xAOD::TrackParticleContainer Output: ActsTrk::TrackContainer and xAOD::TrackParticleContainer Each output TrackParticle has an originalTrackParticle link back to the input track particle and an actsTrack link to the refitted Acts track.

Workflow:

1. Reads TrackParticles from the selected input container
2. Filters tracks that meet the minimum silicon hits criteria (minNoSiHits)
3. For each eligible track particle: a. Retrieves the associated Acts track via the ElementLink b. Passes the track to the ActsFitter tool for GSF refitting c. Stores the refitted track in the output Acts track container
