Distribution of the γ-ray luminosities obtained for each model as a function of the spin-down power. Pink and green dots refer to radio-loud and radio-quiet γ-ray visible objects, respectively. The LAT luminosities (black circles and crosses for radio-loud and radio-quiet objects respectively) have been derived using the energy-flux measurement and the f_Ω value estimated from the fit to the simulated data for the particular spin-down power and radio-loud or quiet state of the LAT pulsars. The dotted line shows the 100% efficiency boundary.
