    1212  It can be employed in order to produce smoother distributions for the tail of a particular observable. I that case the bias function should not impact the physical results obtained, but rather only affect the distribution of the events generated or, in other words, the phase-space sampling.
    13   In this case the events will be first generated and unweighted in presence of this biasing weight. MG5aMC will then reweight these unweighted events by their corresponding bias weight, so as to restore the original physical distributions.
    14   The resulting events made available to the user will therefore be weighted in this case, and distributed in a manner that enhances the statistics in the desired region of phase-space.

    1616  Notice that one can also use the bias function in this way and with a bias weight equal to unity, if something specific must be done with each event, for example on-the-flight plotting.
