The finder selects calorimeter condensates as seeds which contain at least cells.It will also avoid using a condensate that has too many cells from the FCAL beam pipe region: MUFFIN rejects condensates seeds that have more than EMC, HAC1, HAC2 or more than cells in total neighboring the beam pipe. The condensates are sorted into descending order according to their hit ratio. This way the condensates which have a track-like shape come first.
