Energy binning definition

The user must now specify all the bins (s)he wants in the spectra, using nChanBins, chanMin and chanMax parameters. As this can be tedious, standard binnings are provided by setting nChanBins to be . In this case IMA extracts fluxes in bins, i.e. a value nChanBins=0 results in a single wide energy bin, while a value of -4 results in production of 16-channel spectra. The smallest allowed value is -6, corresponding to the 64-channel spectra. Table 5 shows the standard energy bins up to 16 channels.
