Notes. Continuum flux densities are given as the value at 511 keV in units of 10-5 ph cm-2 s-1 keV-1, line and ortho-positronium fluxes are given in 10-4 ph cm-2 s-1, FWHM of the celestial emission line in keV, and the centroid shift ΔE0 = EpeakElab in keV.

(a)

For the Crab and Cyg X-1, no annihilation line has been detected, and 2σ upper limits are given for the flux.
