AI 中文摘要
偏振仪统一日冕和日球层（PUNCH）任务将以高信噪比、高时间分辨率、高分辨率的偏振白光图像对太阳风瞬变进行远程观测。利用不同偏振态，PUNCH的一个重要数据产品将是偏振比图像。在小太阳极限情况下，使用两种具有有限角宽度的简单视线密度分布来近似流或共转相互作用区（SIR/CIR），我们通过分析研究偏振比如何提供三维位置信息以及该估计位置的不确定性。
英文摘要
The Polarimeter to UNify the Corona and Heliosphere (PUNCH) mission will remotely observe solar wind transients with high signal-to-noise ratio, high-cadence, high-resolution polarized white-light images. Using different polarization states, an important PUNCH data product will be polarization ratio images. In the small-Sun limit, and using two simple line-of-sight density distributions with a finite angular width that can approximate a stream or corotating interaction region (SIR/CIR), we analytically investigate how the polarization ratio will provide three-dimensional location information and what the uncertainty in this estimated location is.
