| 43 | //* cx,y,ztrpl = polarization cosines of the current particle * |
| 44 | //* wtrack = weight of the particle * |

| 65 | //* ntrack > 0, mtrack > 0 : energy loss distributed along the * |
| 66 | //* track * |
| 67 | //* ntrack > 0, mtrack = 0 : no energy loss along the track * |
| 68 | //* ntrack = 0, mtrack = 0 : local energy deposition (the * |
| 69 | //* value and the point are not re- * |
| 70 | //* corded in trackr) * |
