jet number lost

Description

Hi,

I add a ee_kt_algorithm set the jet number to 4 ( this algorithm can set a fixed number jets).

The attachment is my tcl file.

I compared:

#add Branch UniqueObjectFinder?/jets Jet Jet
add Branch FastJetFinder?/jets Jet Jet

The first line gives a jet number 2.3 in average and the second result is jet number equal to 4 ( 4 is I hoped ). Why the jet number lost in the first case? I don't see any cut...

Hi,

this is probably because you have Isolated muons, electrons or photons in your event and these are reconstructed as jets by default.

The UniqueObjectFinder removes them from the jet collection.
