| Description: | ||
| Matching L1 to PF/Calo Jets. Used for HLT_VBF paths. | ||
| *Matches PF/Calo Jets to L1 jets from the dedicated seed | ||
| *Adds selection criteria to the leading/subleading jets as well as the maximum dijet mass | ||
| *Separates collections of PF/Calo jets into two categories | ||

There was a problem hiding this comment. myJet1.pt()>pt2? Why pt2? There was a problem hiding this comment. This is the three jets case, where the two jets forming the max mjj have to have pt more than 35GeV but the higher pt one (myJets1) has pt<95 (otherwise it would have been the above two jets case). There was a problem hiding this comment. I should know but I do not - the jets in your pfMatchedJets vector are increasing pt ordered? |

||
| const T & myJetTest = (pfMatchedJets)[0]; | ||
| if (myJetTest.pt()>pt1){ | ||
| output.second.push_back(myJet1); | ||
| output.second.push_back(myJet2); | ||
| output.second.push_back(myJetTest); | ||

There was a problem hiding this comment. do you need to protect against i1==0 || i2==0? There was a problem hiding this comment. i2 should not be able to be ==0 by construction (j=i+1,...). Also, I think that it is safe even without i1==0 protection, because of the pt>pt1 requirement (in the if above there is a req for myJet1.pt<=pt1 so if i1 = 0 it will fail the statement at the end) |

There was a problem hiding this comment. could you not avoid the copy of the output jets by making your interface a std::pair< unique_ptr<std::vector>, unique_ptr<std::vector> > ? There was a problem hiding this comment. I'm not sure if I understand the question. There was a problem hiding this comment. you currently do std::pair<vector,vector> output = categorize(...); [eg, you create each vector 3 times] instead something like std::pair< unique_ptr<std::vector>, unique_ptr<std::vector> > output = categorize(...); There was a problem hiding this comment. I tried doing similar thing at the very beginning but couldn't make it work with doing .put(output.first). I can try again if it is really an issue? There was a problem hiding this comment. copying things is an issue - what problems did you run into? There was a problem hiding this comment. I couldn't make it compile at the beginning so my colleagues showed me how they were doing it in their analysis code. Do I need to change this? There was a problem hiding this comment. lets fix as a followup PR this week. please let me know what problems you had. |

i1 and i2 are not used. they can be removed.
