Abstract	The objective of this proposal is to study the extent of diffuse emission from positron annihilation and the decay of Al-26 in our Galaxy by creating deeper and more uniform exposure maps at medium Galactic latitudes. We ask that INTEGRAL devote 2 Ms in AO16 and 2 Ms in AO17 to observing mid-latitude regions of the Inner Galaxy that are underexposed compared with regions near the Plane. The survey regions are bounded by Galactic longitude and latitude -70 deg < l < 70 deg and 7 deg < b < 33 deg. Around 10%-50% of this survey area has 100-500 ks of exposure time at present. In these regions, the proposed observations will add a minimum of 200 ks per AO which, after two observing cycles, represents an increase in exposure time of > 50%-100% compared with archival data. This proposal will build a legacy dataset that is of interest to a wide community of scientists given the variety of sources present and given how the new data complements ongoing surveys of the Galactic Plane, Bulge, and Center.

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.
