The main function of ibis_binning is to split the data into energy and time bins. The number of the time and energy bins depend on the purpose of the analysis. The user can choose if the binning is done for imaging, spectral extraction, or light curve production. Typically just one bin in time and few bins in energy are chosen for the image production; one time bin and many energy bins for spectral extraction; many time bins and just few energy bins for timing analysis.
This step is repeated for each Science Window in the observational group. The shadowgram is created for each energy interval. Script ibis_binning combines the following executables:
