The only published description of the solar wind sector (SS) term used for the reference level in the post-event and real-time derivation of the Polar Cap (PC) indices, PCN (Polar Cap North) and PCS (Polar Cap South), in the version endorsed by the International Association for Geomagnetism and Aeronomy (IAGA) is found in the commented publication, Janzhura and Troshichev: Identification of the IMF sector structure in near-real time by ground magnetic data, Annales Geophysicae, 29, 1491–1500, 2011. Actually, the publication has served as a basis for the index endorsement by IAGA in 2013. However, neither the illustrations nor the results presented there have been derived by the specified near real-time method. Figures 1, 6, 7, and 8 display values derived by post-event calculations based on daily medians smoothed over 7 d centred on the day of interest. Figures 2, 3, and 4 display observed values smoothed over 7 d, while the remaining Fig. 5 displays averages over 4 months. In summary, there are strong disagreements between indications in the title, abstract, and statements in the text compared to the actual results and their illustrations.

Janzhura和Troshichev（2011）对“通过地磁数据近乎实时地确定IMF部门结构的评论”的评论

事件和实时推导Polar Cap（PC）指数，PCN（Polar Cap North）和PCS（Polar Cap South）时用于参考水平的参考水平的太阳风部门（SS）术语的唯一公开描述。 ，在受评论的出版物Janzhura和Troshichev中找到了国际地磁与航空学协会（IAGA）认可的版本：通过地磁数据Annales Geophysicae几乎实时地识别了IMF部门的结构，29，1491–1500，2011年。实际上，该出版物已成为IAGA在2013年认可该指数的基础。但是，此处显示的插图或结果均未通过指定的近实时方法得出。图1、6、7和8显示的是通过事后计算得出的值，这些计算是基于以关注日为中心经过7天平滑的每日中位数得出的。图2、3和4显示了在7 d内平滑的观测值，而其余的图5显示了4个月的平均值。总之，与实际结果及其插图相比，标题，摘要和文本中的说明之间存在强烈分歧。
