12 * Lemagn = flag for magnetic field (set by Emfgeo) *
14 * Xemf = x-coordinate of the end point in the magnetic field *
15 * Yemf = y-coordinate of the end point in the magnetic field *
16 * Zemf = z-coordinate of the end point in the magnetic field *
18 * Uemf = u-cosine of the end point in the magnetic field *
19 * Vemf = v-cosine of the end point in the magnetic field *
20 * Wemf = w-cosine of the end point in the magnetic field *
22 * dedxem = current de/dx for electrons/positrons *
23 * demelf = energy loss/gain in EM fields *
25 * Intrck = flag for tracking initialization: it must be set to *
26 * zero every time the trajectory direction has changed *
27 * from the previous call to Emfgeo *
