Faraday rotation provides a valuable tracer of magnetic fields in the interstellar medium; catalogs of Faraday rotation measures provide key observations for studies of the Galactic magnetic field. We present a new catalog of rotation measures derived from the Canadian Galactic Plane Survey, covering a large region of the Galactic plane spanning 52 < l < 192, −3 < b < 5, along with northern and southern latitude extensions around l ≈ 105. We have derived rotation measures for 2234 sources (4 of which are known pulsars), 75% of which have no previous measurements, over an area of approximately 1300 deg². These new rotation measures increase the measurement density for this region of the Galactic plane by a factor of 2.

法拉第自转为星际介质中的磁场提供了宝贵的示踪剂；法拉第自转测量目录为银河磁场的研究提供了关键观察结果。我们提出了一个来自加拿大银河平面调查的新旋转测量目录，涵盖了银河平面的大片区域，跨越 52 < l < 192, -3 < b < 5，以及大约l ≈ 105 的南北纬度延伸。我们已经推导出了 2234 个源（其中 4 个是已知脉冲星）的旋转测量，其中 75% 以前没有测量过，分布在大约 1300 度²的区域内。这些新的旋转测量将银河平面这一区域的测量密度增加了 2 倍。
