Does the Jet variable contain all the jets, or the main one ?

Description
Hello,
I am currently a master student and I am discovering DELPHES' features. One thing on which I cannot find an answer online is the following:
When generating e.g semi-leptonic events, a "jet" branch is contained in the TTree of the resulting .root file.
However, there are often several jets per event. My question then is: how is computed e.g the Jet.energy, Jet.momentum.x etc.. ? Is it the total energy/momentum of all the jets ? Or is there some jet selection/ordering, and only the main-jet energy is available (and if so, what is the type of selection/ordering)? (Or another option).
Please feel free to point me to a paper if this was already explained somewhere else.
Best,
Dimitri
