论文摘要
我报告了一种新型3D重建方法的验证和测试，而不是从单个快照的角度获得冠状等离子体特性。我在2021年首次报告了该方法，此后我将其命名为冠状区域或“ Crobar”方法。该测试是用Muram 3D MHD模拟的多个立方体进行的，该模拟提供了类似冠状的“地面真相”，可以与该模拟进行重建方法并进行比较。我发现该方法做得很好，恢复了最近从穆拉姆模拟中报道的类似冠状面纱的特征，并且人们担心这些特征会从有限的角度来阻止有效的3D冠状结构恢复。我还发现，在$ \ sim 45 $至90度之间的第二个视角确实可以显着改善重建。两个具有软X射线温度响应（高于5 MK的峰值）的不同通道足以使Crobar的光学薄观测值足够；除此之外，一套类似AIA的EUV通带，覆盖3-8 MK温度范围。
I report on validation and testing of a novel 3D reconstruction method than can obtain coronal plasma properties from a single snapshot perspective. I first reported on the method in 2021, and I have since named it the Coronal Reconstruction Onto B-Aligned Regions, or 'CROBAR', method. The testing was carried out with a cube from a MURaM 3D MHD simulation, which affords a coronal-like 'ground truth' against which the reconstruction method can be applied and compared. I find that the method does quite well, recovering the 'coronal veil'-like features recently reported from the MURaM simulations, and allaying concerns that these features would thwart recovery of valid 3D coronal structure from a limited number of perspectives. I also find that a second perspective at between $\sim 45$ and 90 degrees, does significantly improve the reconstructions. Two distinct channels with Soft X-Ray like temperature response (peaking above 5 MK) would suffice for CROBAR's optically thin observables; barring that, a suite of AIA-like EUV passbands, with good coverage of the 3-8 MK temperature range.
