Note: I do not know right now why this source generated so many fewer gamma rays than the one above (470 vs. 1842). Nominally Vela is brighter. I used the source specifications exactly as they were given in the XML files in the repository.
(11 Nov 2004): One reason for the difference is that the flux specification in the science tools checkout-era vela.txt was for the 'off-pulse' phase of the pulsar. This is 9.28e-7 vs. 2.3e-6 for the PulsarSpectrum source above. The ratio is ~2.5, so it doesn't explain the full factor of ~4 difference.
Also, note that the SpectralIndex specification for the GalPulsars sources is for the energy spectrum not the (usual for us) photon spectrum, so the index values given to GalPulsars have to be (photon spectral index) + 1.
