Detailed Description

Select truth particles to be used as 'seeds' of reconstruction algorithms, e.g. track fitting and track finding.

This pre-selection could help guarantee quality of the 'seeds', i.e. to avoid empty proto track (no recorded hits for the particle). In addition, it could help save unnecessary reconstruction time. For instance, when investigating performance of CombinatorialKalmanFilter (CKF), we might be interested in its performance for only truth particles with pT and number of recorded hits (on sensitive detectors) safistying provided criteria (input measurments of CKF are still recorded hits from all possible particles). Then we could use particles only satistying provided criteria as the 'seeds' of CKF instead of handling all the truth particles.
