Table 1: Average number of elementary charges given to the targets made of aluminum (Al), iron (Fe), or graphite (C) by a particle of nominal size dn (i.e. positive sign means that the target charged positively, the particle negatively). The precharge is the number of elementary charges given on average to the cogwheel. Error is $\pm $13%.
