JetID Certification Version 5.0 for p14
(Dec 3, 2003)

- valid for p14 tmb-fixed data

JetID cuts -  0.05 < EMF < 0.95
-  CHF < 0.4
-  HotF < 10
-  n90 > 1
-  l1set / (jet pT * (1 - CHF)) > 0.4 (in CC, EC) or > 0.2 (ICD)

where CC region is defined as |eta_det|<0.8
           EC region is defined as |eta_det|>1.5
           ICD region is defined as 0.8 < |eta_det|<1.5

For runs < 172359 we had L1 calorimeter redout only up to |eta|=2.4. Starting from run 172359 the readout was extended up to |eta|=3.2 (for details see CalRunRanges.txt). Outside this region on has to relay on old jetID cut using the f90 variable: f90 < 0.5 or CHF < 0.15 (where f90 = n90/nitem)

The implementation of the selection criteria will soon appear in d0correct packages. So far, here is the link to example implementation . Still not implemented a remapping of L1 towers in ICD region from >3.8 eta region to ICD.
