Scientific paper

The results of an observation of the galactic center in the MeV gamma ray domain are discussed in relation to measurements of other experiments. The results were obtained from the reduction of old balloon flight measurement data using the maximum entropy method, that was proved to be superior to other development methods for the calculation of celestial charts from Compton telescope data. It is shown that, with the assumption of a non-point source of the line radiation of the radioactive Al-26, the flight measurement data obtained with very different instruments agree within the errors of the measurements. The measured distribution of Al-26 agrees with that of CO in the galactic plane, with the measured distribution in Novae (N2 model), and with the thin hot plasma model (soft X domain).
