    keyword=Neutrons in Neutron Array

    The attached plot shows some indication of recoiled neutrons being detected by Neutron Array. Variable being plotted is:
    chain.Draw("NA.tr.tof",ct&&"NA.tr.tof>150&&NA.tr.tof<550&&fEvtHdr.fEvtType==5") ;

    and the cuts applied were:
    TCut ct2by1="CT.ct_2by1*1e9","CT.ct_2by1*1e9>98&&CT.ct_2by1*1e9<100.5&&L.tr.n==1&&R.tr.n==1&&L.s2.nthit==1&&R.s2.nthit==1" ;
    TCut mrec="SK.Mrecoil<.95&&SK.Mrecoil>.93" ;
    TCut pm= "SK.pmiss<.4&&SK.pmiss>.2";
    TCut em="SK.emiss<0.03&&SK.emiss>0.01";

    TCut ldp="L.gold.dp<0.02&&L.gold.dp>-0.05" ;
    TCut lth= "abs(L.gold.th)<0.075";
    TCut lph= "L.gold.ph<0.015&&L.gold.ph>-0.033";

    TCut rdp= "abs(R.gold.dp)<0.055";
    TCut rth= "abs(R.gold.th)<0.075";
    TCut rph= "abs(R.gold.ph)<0.04";
