Abstract Our proposal 0820024 to examine the longitude distribution of the 511 keV positron annihaltion emission from the inner galaxy was accepted but awarded only half of the time estimated as necessary. The TAC encouraged us to resubmit in AO9 to achieve the required exposure. Results to date are encouraging and we request a further 2.5 Ms of observations employing the successful chopping pointing strategy to observe alternately fields at (l,b)= (+/-15deg,0deg), that cover both the inner disk and the outer bulge region, so providing a total of 5 Ms.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
