11. k end calculations themselves do not allow the use of a broad energy band e g 20 keV to 10 MeV The underlying algorithm in OTE calculates the average performance across a user defined continuum energy band given the flux of the source in that band However the sensitivity of the instruments can vary enormously over their energy ranges In addition the gamma ray instruments can have very rapid changes in sensitivity in a comparatively small range of energies especially around 511 keV Also many most gamma ray sources exhibit steep spectra so that they are very much fainter at higher energies Even for hard sources including the highest energies will result in very low S N due to the relatively high background at MeV energies compared to the source flux For these reasons in previous AOs OTE was restricted to energy bands which are narrower than the entire instrumental bandpass Of course the prospective observer may be in a situation where the continuum range of interest is rather wide To allow this the front end GUI of OTE allow the user to specify a wider band OTE splits the input energy range into narrower sub bands and assuming a power law spectrum with the flux and spectral index as user inputs calculates the flux within each sub band It then performs individual calculations on these sub bands of the S N or observation duration and finally combines these results into a global figure for the entire input energy band 3 3 Hints
