A tracker hit on a cylindrical surface that runs parallel to the z-axis - the hit is stored as:
x,y,z, center(x,y), dRPhi, dz
where (x,y,z) is the position in global cartesian coordinates, center(x,y) is the center of the cylinder and Rphi and z are the measurement errors. More...

Detailed Description

A tracker hit on a cylindrical surface that runs parallel to the z-axis - the hit is stored as:
x,y,z, center(x,y), dRPhi, dz
where (x,y,z) is the position in global cartesian coordinates, center(x,y) is the center of the cylinder and Rphi and z are the measurement errors.

Note the radius of the cylinder is given by R=sqrt( dx^2c+ dy^2 ) and dx=x-x_c, dy=y-y_c.
