Hall C ROOT/C++ Analyzer (hcana)
|
Analyze a package of horizontal drift chambers.
Uses the first letter of the apparatus name as a prefix to parameter names. The paramters, read in the Setup method, determine the number of chambers and the number of parameters per plane.

Find a set of tracks through the drift chambers and put them into the tracks TClonesArray. Tracks are in the detector coordinate system.

this function calculates the psi coordinate of the intersection of a ray (defined by ray) with a hms wire chamber plane. the geometry of the plane is contained in the coeff array calculated in the array hplane_coeff Note it is call by MINUIT via H_FCNCHISQ and so uses double precision variables
the ray is defined by x = (z-zt)*tan(xp) + xt y = (z-zt)*tan(yp) + yt at some fixed value of zt* ray(1) = xt ray(2) = yt ray(3) = tan(xp) ray(4) = tan(yp)

The logic is 0) Put all space points in a single list 1) loop over all space points as seeds isp1 2) Check if this space point is all ready in a track 3) loop over all succeeding space pointss isp2 4) check if there is a track-criterion match either add to existing track or if there is another point in same chamber make a copy containing isp2 rather than other point in same chamber 5) If hsingle_stub is set, make a track of all single stubs.
