Here is 7 records of 13 elements. elements 6 .. 13 are various group parameters (Par1 .. Par8) which are used in group's specific routines.
FNCRec program have access to this parameters via grp2par(ParN,Gr) array, filled in fn2mdb subroutine
For all groups Par1 is relative Group gain (all module energies inside of the group are multiplied by Par1).
Par3 is Noise Cut for single module in the group.
Par4 is Cut on Cluster Energy, calculated over all modules of MainCalo (groups 1-4) and of Preshower (groups 5-6).
Par5-6 are used in coordinates reconstruction

Here is translation for parameters (Par1 .. Par8):
