With the help of the IBIS_SI_inEnergyValues parameter you
can specify the desired energy bins. Apart from specifying the energy bins, you should also rebin the responce matrix, see Section
9.5 for the detailed discussion on how to do this. The rebinned response matrix should then be linked to the spectrum you produce. This can be done by setting the parameter
SCW2_ISPE_idx_isgrResp="your_rebinned_matrix.fits". This
parameter defines the name of the response matrix that would be added
to the header of the spectrum file. Warning:This parameter
is a hidden one. Thus you should either provide the value of
this parameter during the script launch
ibis_science_analysis SCW2_ISPE_idx_isgrResp="your_rebinned_matrix.fits"or press "hidden"-button and set this parameter on the SPE page.
