论文摘要
我们分析了星际中性气体流入到地球层的温度，方向和速度之间相关性的原因，这是在IBEX-LO仪器在板上星际边界探索者（IBEX）上进行的观察结果中获得的。我们指出，这种相关性是无法测量进入仪器的原子的速度以及观测值限制在观测过程中仪器执行的太阳周围的短轨道弧的限制。我们证明，没有能力测量速度的能力，但是能够沿较长的轨道弧进行观测，或者从太阳周围的轨道上的至少两个遥远的位置进行观察，可以打破参数相关性。但是，这需要能够调整相对于航天器旋转轴的仪器的镜头，例如计划中的IMAP-LO摄像头在船上的星际映射和加速探针（IMAP）。
We analyze the reasons for the correlation between the temperature, direction, and speed of the interstellar neutral gas inflow into the heliosphere, obtained in analyzes of observations performed by the IBEX-Lo instrument onboard Interstellar Boundary Explorer (IBEX). We point out that this correlation is the combined result of the inability to measure the speed of the atoms that enter the instrument and the restriction of the observations to a short orbital arc around the Sun performed by the instrument during observation. We demonstrate that without the capability to measure the speed, but with the ability to perform observations along longer orbital arcs, or from at least two distant locations on the orbit around the Sun, it is possible to break the parameter correlation. This, however, requires a capability to adjust the boresight of the instrument relative to the spacecraft rotation axis, such as that of the planned IMAP-Lo camera onboard the Interstellar Mapping and Acceleration Probe (IMAP).
