+Description: Computes HT and MHT from phase-1-like jets
+
+*** INPUT PARAMETERS ***
+  * sin/cosPhi: Value of sin/cos phi in the middle of each bin of the grid.
+  * etaBinning: vdouble with eta binning (allows non-homogeneous binning in eta)
+  * nBinsPhi: uint32, number of bins in phi
+  * phiLow: double, min phi (typically -pi)
+  * phiUp: double, max phi (typically +pi)
+  * {m}htPtThreshold: Minimum jet pt for HT/MHT calculation
+  * {m}htAbsEtaCut: 
+  * pt/eta/philsb : lsb of quantities used in firmware implementation
+  * outputCollectionName: string, tag for the output collection
+   * inputCollectionTag: tag for input jet collection
