GROUP igamgp {0}
This keyword specifies the binning of the discrete photon spectral lines into histograms for use in the γ-dose computations and PRINTLIB output. The same bins are used for the approximate γ spectra generated when the SPEK keyword is used in the condense phase of the library data processing
The default (igamgp = 0) case produces the γ-spectrum data in a 24-energy group structure.
The igamgp = 1 option outputs the γ-spectrum data in the 22-group 'Steiner' structure.
Note that the structure determined by igamgp is also used when TAB4 is specified to produce a file of the γ-spectrum data.
An example where the 22-group Steiner structure is requested for the gamma spectrum:
