Detailed Description

This class runs the Acts seeder over the MVTX measurements to create track stubs for the rest of the stub matching pattern recognition. The module also projects the MVTX stubs to the INTT to find possible matches in the INTT to the MVTX triplet.

	)

private

Solutions to the circle intersection are (xplus, yplus) and (xminus, yminus). The intersection of the two circles occurs when (x-x1)^2 + (y-y1)^2 = r1^2, / (x-x2)^2 + (y-y2)^2 = r2^2 Here we assume that circle 1 is an sPHENIX layer centered on x1=y1=0, and circle 2 is arbitrary such that they are described by x^2 +y^2 = r1^2, (x-x0)^2 + (y-y0)^2 = r2^2 expand the equations and subtract to eliminate the x^2 and y^2 terms, gives the radial line connecting the intersection points iy = - (2*x2*x - D) / 2*y2, then substitute for y in equation of circle 1

Circle fit to a given set of data points (in 2D) This is an algebraic fit, due to Taubin, based on the journal article G. Taubin, "Estimation Of Planar Curves, Surfaces And Nonplanar Space Curves Defined By Implicit Equations, With Applications To Edge And Range Image Segmentation", IEEE Trans. PAMI, Vol. 13, pages 1115-1138, (1991) It works well whether data points are sampled along an entire circle or along a small arc. It still has a small bias and its statistical accuracy is slightly lower than that of the geometric fit (minimizing geometric distances), It provides a very good initial guess for a subsequent geometric fit.

Perform circle/line fits with the final MVTX seed to get initial point and momentum estimates for stub matching

Circle radius at x,y center Note - units are sPHENIX cm since we are using TrkrClusters

If the xy position is O(100s) microns, the initial vertex finder will throw an eigen stepper error trying to propagate from the PCA. These are likely bad seeds anyway since the MVTX has position resolution O(5) microns. Units are cm

Return statement doesn't matter as x = nan will be caught

Now determine the line tangent to the circle at this point to get phi The slope of the line connecting the circle center and PCA is m = (y0-y)/(x0-x). So the perpendicular slope (i.e. phi) is then -1/m For some reason the phi value comes back from atan2 off by a factor of pi for positive charged tracks, hence the check

m is slope as a function of radius, B is z intercept (vertex)

normalize to 0 < theta < pi

0.3 conversion factor, 1.4=B field, 100 convert R from cm to m Get a very rough estimate of p

The only thing that is really needed for the propagation is the direction

Project to INTT and find matches

Add possible matches to cluster list to be parsed when Svtx tracks are made

We need to determine the closest point on the circle to the origin since we can't assume that the track originates from the origin The eqn for the circle is (x-X0)^2+(y-Y0)^2=R^2 and we want to minimize d = sqrt((0-x)^2+(0-y)^2), the distance between the origin and some (currently, unknown) point on the circle x,y.

Solving the circle eqn for x and substituting into d gives an eqn for y. Taking the derivative and setting equal to 0 gives the following two solutions. We take the smaller solution as the correct one, as usually one solution is wildly incorrect (e.g. 1000 cm)

Figure out which of the two roots is actually closer to the origin

Check that the projection is within some reasonable amount of the segment to reject e.g. looking at segments in the opposite hemisphere. This is about the size of one intt segment (256 * 80 micron strips in a segment)

Z strip spacing is the entire strip, so because we use fabs we divide by two
