  We present a novel method for sorting events. So far, single variables like
flow vector magnitude were used for sorting events. Our approach takes into
account the whole azimuthal angle distribution rather than a single variable.
This method allows us to determine the good measure of the event shape,
providing a multiplicity-independent insight. We discuss the advantages and
disadvantages of this approach, the possible usage in femtoscopy, and other
more exclusive experimental studies.
