The Galactic Plane Infrared Polarization Survey (GPIPS) seeks to characterize the magnetic field in the dusty Galactic disk using near-infrared stellar polarimetry. All GPIPS observations were completed using the 1.83 m Perkins telescope and Mimir instrument. GPIPS observations surveyed 76 deg 2 of the northern Galactic plane, from Galactic longitudes 18°–56° and latitudes −1° to +1°, in the H band (1.6 μ m). Surveyed stars span 7th–16th mag, resulting in nearly 10 million stars with measured linear polarizations. Of these stars, ones with m H < 12.5 mag and polarization percentage uncertainties under 2% were judged to be high quality and number over one million. GPIPS data reveal plane-of-sky magnetic field orientations for numerous interstellar clouds for A V values to ∼30 mag. The average sky separation of stars with m H < 12.5 mag is about 30″, or about 60 per Planck...

银河平面红外极化调查（GPIPS）：数据发布4

银河平面红外极化调查（GPIPS）试图使用近红外恒星极化技术来表征尘土飞扬的银河盘中的磁场。所有GPIPS观测都是使用1.83 m的珀金斯望远镜和Mimir仪器完成的。GPIPS观测在H波段（1.6μm）范围内，从银河经度18°–56°和纬度-1°至+ 1°观测了北银河平面的76度2。被调查的恒星跨越7至16磁极，产生了近1000万颗具有测量的线性极化的恒星。在这些恒星中，m H <12.5 mag且极化百分比不确定度低于2％的恒星被认为是高质量的，并且数量超过一百万。GPIPS数据揭示了许多星际云的天空平面磁场方向，其AV值约为30 mag。m H <12的恒星的平均天空间隔。
