java.lang.Object

org.jlab.analysis.eventmerger.EventMerger

public class EventMerger
extends Object

Tool for merging of signal and background events Usage : bg-merger -i [signal event file] -o [merged file] [input1] [input2] .... Options : -d : list of detectors, for example "DC,FTOF,HTCC" or "ALL" for all available detectors. Use DC1, DC2 or DC3 to select the DC region (default = ALL) -l : preserve initial hit order (for compatibility with truth matching, 0-false, 1-true (default = 1) -n : maximum number of events to process (default = -1) -r : reuse background events: 0-false, 1-true (default = 1) -s : suppress double TDC hits on the same component, 0-no suppression, 1-suppression (default = 1) -t : list of hit OrderTypes to be saved (default = NOMINAL,BGADDED_NOMINAL,BGREMOVED,BGREMOVED_BG,DECREMOVED,DECREMOVED_BG) -x : background scale factor (default = 1)
