[1]在SV Badman等人的论文“Cassini在土星观测离子和电子束及其与红外极光弧的关系”中，（Journal of Geophysical Research，117，A01211，doi：10.1029/2011 JA 017222，2012），分析错误出现在摘要第15、17、19、20、23、26、27、32、33-39、41段和第5节中。更正后的文本出现在这里。[2]在巴德曼等人的论文中，介绍了卡西尼号航天器测得的高纬度、场向电流的磁特征，并将其与土星中午电离层的极光弧联系起来。用于确定气流向上或向下方向的分析最初假设当前层相对于卡西尼号是静止的。在论文的后面，这些特征被解释为向上和向下的场向电流的相邻层在卡西尼上空向极移动，速度比卡西尼快。然而，讨论忽略了这种快速向极运动的一个结果：卡西尼号测量的磁场方位角分量的偏转所确定的电流的向上或向下方向，将相对于“静止”分析反向。
[1] In the paper “Cassini observations of ion and electron beams at Saturn and their relationship to infrared auroral arcs” by SV Badman et al.(Journal of Geophysical Research, 117, A01211, doi: 10.1029/2011JA017222, 2012), analysis errors appear in the Abstract, paragraphs 15, 17, 19, 20, 23, 26, 27, 32, 33–39, 41, and section 5. The corrected text appears here.[2] In the paper by Badman et al. the magnetic signatures of high-latitude, field-aligned currents measured by the Cassini spacecraft were presented, and related to auroral arcs in Saturn’s noon sector ionosphere. The analysis used to determine the upward or downward direction of the currents initially assumed that the current layers were stationary relative to Cassini. Later in the paper, these features were interpreted as adjacent layers of upward and downward fieldaligned currents moving poleward over Cassini, at a speed faster than Cassini. However, the discussion neglected one consequence of this suggested fast, poleward motion: that the upward or downward direction of the currents, identified by deflections in the azimuthal component of the magnetic field measured by Cassini, would then be reversed relative to the ‘stationary’analysis.
