This proposal is aimed on obtaining legacy-level observational datasets on the Milky Way Galactic disk. The ultimate goal of the entire project is to have model independent and systematics free measurements of the fluxes in nuclear lines (511 keV annihilation emission and 1.8 MeV Al26) and a broad band spectrum of the Galactic background emission which at different energies is provided either by cumulative emission of faint Galactic source or by interaction of low energy cosmic rays with interstellar medium. Taking into account the unique combination of properties of INTEGRAL instruments - broad band coverage large fields of view and possibilities to eliminate the contribution of discrete sources from the total measured photon flux the proposed strategy is the best possible usage of the valuable INTEGRAL time. Wide mapping of the Milky Way during the campaign of Galactic latitude scans also contributes to the legacy of the INTEGRAL observatory giving the opportunity to study the population of Galactic sources at high latitudes.

本提案旨在获取银河系银盘的传世级观测数据集。本项目的终极目标是实现无模型依赖且无系统误差的核谱线通量（包括511 keV湮灭辐射与1.8 MeV铝-26谱线）测量，以及银河系背景辐射的宽波段能谱——该背景辐射在不同能量区间内，其来源分别为微弱银河源的累积辐射，或是低能宇宙线与星际介质的相互作用。鉴于INTEGRAL（国际伽马射线天体物理实验室）探测器具备宽波段覆盖、大视场的特性，且可从总测量光子通量中扣除分立源的贡献，结合其独特的性能组合，本提案采用的观测策略可实现对宝贵INTEGRAL观测时间的最优利用。在银纬巡天任务中对银河系开展的广域测绘，也将丰富INTEGRAL天文台的传世观测遗产，同时为研究高银纬银河源的分布提供契机。【文本已截断！如需完整内容，请查阅原始数据集】
