  • Definitions of Cuts
hmscleantrack =   hsnum_fptrack != 0
shmscleantrack =  ssnum_fptrack != 0
ccleantrack = hmscleantrack && shmscleantrack
goodctime = loose cut around the cointime peak (3 beam buckets) 
coincut =  ccleantrack && goodctime
tight_coin = ccleantrack && tight cut around cointime peak (1 beam bucket)
ran_coincut = ccleantrack && cut on 4 beam buckets away from the coincidence peak
coincut_ep =  ccleantrack && select_e_cut && sbetacut_p  
select_e_cut = cut on HMS shower and HMS_cerenkov to select electrons
sbetacut_p = select protons from SHMS beta spectrum
