Below are definitions of the structures used in the clas12 dc reconstructions.
Hits
"A DC hit is characterized by superlayer, layer, sector, wire number, and time." - Veronique Ziegler, clas12-offline-software, Hit.java
Hit.java defines the representation of a drift chamber wire hit.
Clusters
"A cluster in the DC consists of an array of hits that are grouped together according to the algorithm of the ClusterFinder class" - Veronique Ziegler, clas12-offline-software, Cluster.java
Segments
"A class to describe segment objects, where a Segment is a fitted cluster that has been pruned of hits with bad residuals" - Veronique Ziegler, clas12-offline-software, Segment.java
Crosses
"The crosses are objects used to find tracks and are characterized by a 3-D point and a direction unit vector." - Veronique Ziegler, clas12-offline-software, Cross.java
Tracks
"A class representing track candidates in the DC. A track has a trajectory represented by an ensemble of geometrical state vectors along its path, a charge and a momentum" - Veronique Ziegler, clas12-offline-software, Track.java
