103 * are removed are timebins which have the 4 zero neighbours;

132 * through the offline reconstruction chain.
133 * The arguments is a pointer to the data, and the name of the new AliROOT file.
134 * Remember to pass the original AliROOT file (the one that contains the original
135 * simulated data) to this object, in order to retrieve the MC id's of the digits.
