Comparing Package Versions: Efficiencies
For Tower A (e.g. run 306000475), the “new” code (v4r060302p10) gives better
efficiencies than the “old” code (v3r0407p10).

Conclusion
Default behaviour of TkrRecon has changed (using
LatIntegration/src/jobOptions/pipeline/readigi_runrecon.txt).
in src/PatRec/Combo/ComboFindTrackTool.cxx:
int m_maxFirstGaps; // Max. number of allowed gaps in the first 3 XY points
int m_maxTotalGaps; // Max. total number of XY gaps in the track
declareProperty("MaxFirstGaps", m_maxFirstGaps = 1);
declareProperty("MaxTotalGaps", m_maxTotalGaps = 2);
but in src/track/FindTrackHitsTool.cxx:
double m_rej_sigma; // The rejection track limit for being inside an active
// area with no cluster
double m_max_gap_dist; // Max. allowed error in mm when testing for gap edges
int m_maxGaps; // Max. number of gaps (hitType = UNKNOWN) to allow on a track
int m_maxConsecutiveGaps; // Max. # of consecutive gaps (hitType = UNKNOWN)
// allowed
declareProperty("GapRejectionSigmaSize", m_rej_sigma = 2.);
declareProperty("GapMaxRejectionSize", m_max_gap_dist = 10.);
declareProperty("MaxGaps", m_maxGaps = 0);
declareProperty("MaxConsecutiveGaps", m_maxConsecutiveGaps = 0);
