Specific software was developed, using the IDL package and a specific routines contained in the astrolib library, to convert GRBM spectra and response matrices in FITS-OGIP format to be used and tested with standard spectral analysis software packages like FTOOLS and XSPEC.
This has been done not only with the 240 channels spectra and response matrices, but also for the analysis of ratemeters data, by expressing the response in the GRBM and AC bands in the form of a response matrix and the counts in the two bands in the form of 2-channels spectra.
