Results of the fits of our simulated 511 keV emission spatial distributions due to all nucleosynthesis positrons, with an SN Ia escape fraction of 5% for 56Ni positrons, and for the three halo GMF configurations, to about 8 years of INTEGRAL/SPI observations.

Notes. The N, D, and X models are those with no, dipole, and X-shape halo fields, respectively. The UW model is the updated best-fit analytical model. Columns 2−4 give the fitted flux in 10-4 ph cm-2 s-1 for the inner bulge, outer bulge, and disk components. Column 5 gives the maximum likelihood ratio. For the sake of completeness, the Crab and Cygnus X-1 fluxes in the 508.5–513.5 keV band were also fitted during the fit procedure.
