A special data card: NOSC is foreseen to remove the SiCAL clusters from ENFLW objects. This works on POT/DST/MINI.
However, be careful: when writing MINIs from DST/POT with NOSC, the SiCAL clusters are NOT saved on the MINIs and will not be recovered when reading these MINIs even without NOSC. This is OK for private productions; the official MINIs are produced with the SICAL clusters in energy flow objects.
