Jets (Cone R=0.7) Standard Cuts

 Jets reconstructed using the cone algorithm with standard jet ID applied.
 They are a repeated set similar to Jets ALL (Cone=0.7).

 N
 -----
 The number of jets in the event.  I see a two-peaked distribution with 
 2 jets most-likely and 0 jets next-most-likely.  That is understandable
 given that QCD events tend to have at least two or more jets, balancing 
 in Et.  Other events have either two or more jets that fall below 
 threshold (typical of MinBias) or no jets at all above threshold.

 There are lots of events with 3 or more jets and even a few with 8.
 
 Et
 -----
 The Et of jets.  We don't save jets reconstructed with Et less than 8 GeV.

 Eta
 -----
 Jet eta.  There must be a fairly heavy trigger bias as jets are 
 produced approximately flat in eta at a given Et. 

 
 Phi
 -----
 Jet phi.

 EMF
 -----
 The electromagnetic fraction of jets, including electrons.

 Coarse hadronic fraction. This is a selection criteria for jets.
