Detailed Description

Jet Et calibration LUT.

Author

Robert Frazier & Greg Heath

Date

May 2006

Input is 10 bit Et and tau veto bit. Separate LUTs for different eta. Output is 6 bit rank (for jet sorting).

Modified March 2007 to remove the actual calculation to a separate class Modified October 2008 to have separate LUTs for each eta, as in the firmware
