  1. Exp49run746 Hold efficiency significantly low (Monitored by MonTA)

  2. L0 data in E49R746 HadronC DST L0 GDL monitor Hold MonTA ~487000 L0 MonTA data got wrong after ~487000 events. GDL L0 monitor data seems still usable.

  3. Checked svd2_me_mon for HadronC DST, using svdL0Trigger() modified to use L0 in Datgdl_subt  Though the occupancy is similar, M.E. ~ 0% after 487000  indicating event slip of whole SVD data?
