 * This  is not valid for any kind of plane orientation
 * choice: to use it you MUST choose a plane described by u
 * and v axes with v coincident with the wire (and u orthogonal
 * to it, obviously).
 * The hit will be described by 8 coordinates:
 * w_x1, w_y1, w_z1, w_x2, w_y2, w_z2, rdrift, zreco
 * where w_ji (with j = x, y, z and i = 1, 2) are the wire
 * extremities coordinates; rdrift = distance from the wire (u
 * coordinate in the plane) and zreco = coordinate along the
 * wire (w2 -w1) (in the plane reference frame, v coordinate).
