i have a problem i have a root file which contain some branches and i wanted to have new variable which in principle some thing to get from other 3 variables you may understand better from the attached root file and plotting script
i wander if i am doing the correct thing when i tried to build my new variable in the script called Link120 at line 113 or not?
if i changed the definition
Link120 = "L"+std::to_string(tmlink[j])+"_S_"+std::to_string(tmsec[j])+"_R_"+std::to_string(tmwh[j]);
Link120 = "L"+std::to_string(*tmlink)+"_S_"+std::to_string(*tmsec)+"_R_"+std::to_string(*tmwh);
i got different results which in principle makes more sense but i am not sure what is the best to access and array variable by just call it by Variable[j] or *Variable
