Description
Base cell for the cellular automaton A cell is defined by two crosses and its
state
Returns the calculated center and radius of a circle from three points.
A simple algorithm to calculate the center and radius of a circle that passes
through three points
Returns the parameters of a fit with a circle to hits in the the CLAS12 where
the solenoid field bends the particle path into a helix.
Circle fit using the Karimaki algorithm.
A cluster in the BST consists of an array of hits that are grouped together
according to the algorithm of the ClusterFinder class
The fit parameters of a line fit returned by HelicalTrackFitter
A fitter which does sequential fit (for x, y coordinates) and then (for r, z
coordinates) to a line using LineFitter.
Status of the HelicalTrackFit
The crosses are objects used to find tracks and are characterized by a 3-D
point and a direction unit vector.

The fit parameters of a line fit returned by HelicalTrackFitter
A fitter which does sequential fit (for r, phi coordinates) to a circle using
CircleFitter and then (for r, z coordinates) to a line using LineFitter.
Status of the HelicalTrackFit
A class describing a helix; the helix parameters are field of the track
object These parameters are private and accessed by getters: _dca; //
distance of closest approach to the z-axis in the lab frame _phi_at_dca; //
azimuth at the DOCA _curvature; // track curvature = 1/R, where R is the
radius of the circle _Z0; // intersect of the helix axis with the z-axis
_tandip; // tangent of the dip angle = pz/pt
Has a method getPointAtRadius(double r) which returns the point position
along the helix at a given radial distance from the lab origin.
A class with methods used to find lists of crosses.
A hit characterized by layer, sector, wire number, and Edep.
A class to fill in lists of hits corresponding to reconstructed hits
characterized by the strip, its location in the detector (layer, sector), its
reconstructed time.
The fit parameters of a line fit returned by LineFitter
A least square fitting method For a linear fit,f(a,b)=a+bx taking y errors
into account

candidates in the BST
A class with methods used to find lists of crosses.
A fitter which does sequential fit (for r, phi coordinates) to a circle using
CircleFitter and then (for r, z coordinates) to a line using LineFitter.
Status of the HelicalTrackFit
