Notes. Cases A, B, C correspond to our models of all nucleosynthesis positrons with their mean injection rates and the three transport scenario considered. Case W correspond to the best-fit reoptimised Weidenspointner model. Columns 2 − 4 give the fitted fluxes in 10-4 ph cm-2 s-1 for the inner bulge, outer bulge, and disk components, respectively. The numbers in parentheses are the scaling factors applied to our models in the fit. Column 5 gives the Maximum Likelihood Ratio.
