 *
 * Description:
 *
 * Note the following: with the arrival of ITTF it is now possible to
 * store the numberOfPoints for every detector individually. Before
 * that and because of the way the tables were defined TPC and FTPC were
 * one and the same. This caused confusion. However, since we have to
 * stay backwards compatible the "old way" is still working.
 * If
 * a) mNumberOfPoints == 0 the new encoding is the one to use, i.e.,
 *    mNumberOfPointsTpc
 *    mNumberOfPointsFtpcWest 
 *    mNumberOfPointsFtpcEast 
 *    mNumberOfPointsSvt 
 *    mNumberOfPointsSsd 
 *    are the ones that count
 * b) mNumberOfPoints != 0 then we still loaded the info from
 *    the tables and all is as it was before, i.e., we do not distinguish
 *    between FTPC and TPC.
