星际边界探测器（IBEX）观测到IBEX带状物，它在高能中性原子（ENA）中观测到的大部分天空中延伸。带状物覆盖了一个狭窄的（约20°-50°）区域，被认为大致垂直于星际磁场。叠加在IBEX带上的是受日鞘过程和性质控制的全球分布通量。这是第二项研究，利用先前开发的技术，从全球分布的通量中分离带中的ENA排放。透明遮罩应用于色带和高发射区域。然后，我们解决了全球分布的通量使用插值方案。此前，带分离技术应用于0.71 keV及以上的IBEX-Hi数据的第一年。在这里，我们将分离分析扩展到0.2千电子伏和五年的IBEX数据，使第一个地图的丝带和全球分布的通量在整个天空的ENA排放。我们的分析表明，在低于0.71千电子伏的能量的带状峰加宽，并演示了明显的变形的鼻子和heliotail的带状。我们展示了日鞘的全球不对称性，包括日尾的偏转和叶片的不同宽度，在日光层磁场的方向，悬垂和压缩的背景下。我们讨论的影响，试图解释丝带的起源的各种概念的丝带地图。因此，我们提出了五年的IBEX带状全球分布的通量准备正式IBEX数据发布的带状和全球分布的通量地图的太阳物理学界分离。
The Interstellar Boundary Explorer (IBEX) observes the IBEX ribbon, which stretches across much of the sky observed in energetic neutral atoms (ENAs). The ribbon covers a narrow (∼20°–50°) region that is believed to be roughly perpendicular to the interstellar magnetic field. Superimposed on the IBEX ribbon is the globally distributed flux that is controlled by the processes and properties of the heliosheath. This is a second study that utilizes a previously developed technique to separate ENA emissions in the ribbon from the globally distributed flux. A transparency mask is applied over the ribbon and regions of high emissions. We then solve for the globally distributed flux using an interpolation scheme. Previously, ribbon separation techniques were applied to the first year of IBEX-Hi data at and above 0.71 keV. Here we extend the separation analysis down to 0.2 keV and to five years of IBEX data enabling first maps of the ribbon and the globally distributed flux across the full sky of ENA emissions. Our analysis shows the broadening of the ribbon peak at energies below 0.71 keV and demonstrates the apparent deformation of the ribbon in the nose and heliotail. We show global asymmetries of the heliosheath, including both deflection of the heliotail and differing widths of the lobes, in context of the direction, draping, and compression of the heliospheric magnetic field. We discuss implications of the ribbon maps for the wide array of concepts that attempt to explain the ribbon's origin. Thus, we present the five-year separation of the IBEX ribbon from the globally distributed flux in preparation for a formal IBEX data release of ribbon and globally distributed flux maps to the heliophysics community.
