Volume output range should be this way:
1001 NBGX2 = first x node to contain receivers
9000 NEDX2 = last x node to contain receivers
2 NSKPX2 = skip of nodes containing x receivers
501 NBGY2 = first y node to contain receivers
4500 NEDY2 = last y node to contain receivers
2 NSKPY2 = skip of nodes containing y receivers
1 NBGZ2 = first z node to contain receivers
900 NEDZ2 = last z node to contain receivers
2 NSKPZ2 = skip of nodes containing z receivers
80 NTISKP2 = time skip of seismograms (every nth step)
