Building on our successful AO-6 and AO-7 observations we propose a similar observational program dedicated to determining the longitude profile of the asymmetric positron annihilation line radiation from the inner Galaxy first reported by Weidenspointner et al. 2008. Crucial measurements to achieve this goal can be made by applying the successful chopping pointing strategy to fields at (lb)= (+/-15deg0deg) that cover both the inner disk as well as the outer bulge region for a total of 5 Ms. [truncated!
