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.
