// Sort Rank LUT, Eta-Phi part
//
// This LUT determines the dependency of the sort rank on Eta and Phi. 
// It can be used to lower the rank of or to disable muons in certain
// hot detector regions
//
// Inputs:  eta(6 bit) and phi(8 bit)
// Outputs: Rank contribution 2-bit
//
//
//
// PROPOSAL FOR PROGRAMMING
//
// 00   Reduce below all other: rank += 0
// 01   Reduce by half scale:   rank += 64
// 10   Normal operation:   rank += 128
// 11   Switch off:         rank = 0
//
// Switched off muons (code 11 binary) will be disabled completely, also for the matchiing
// by an additional disable-signal.
