The distribution of the weights in each Econe and each Edens bin of the weight table

At the moment the weights are derieved as the mean value of the weights in each bin of the weight table. In order to have a look at these distributions I plot 520 histogramms for each bin of the weight table, to see the distributions in the individual bins of the weight table. This is done by saving a new tree while creating the weight tables, where only Edens, Econe and the weight is stored (separately for tile and LAr). This is one first result (taken only one row in the Econe, that is Econe is unchanged, while Edens changes - which changes also the distribution of the weights!!!!! this is true for each row in Econe and seems to be the same for the opposite charge)

what should be done:

• draw for Edens constant - does that change the Econe?
• have a closer look at tile

One suggestion is that for low energy densities, noise dominates, so that the weight are very low in general. With increasing energy density, the fraction of noise vanishes, and the weight become more or less 1.
