选择一个安静的地区是否影响当地日震的推断?

Does the Selection of a Quiet Region Influence the Local Helioseismic Inferences?

S. C. Tripathy, H. M. Antia, K. Jain, F. Hill

摘要:

我们应用环形图技术的高分辨率多普勒,以估计活跃和安静的区域之间的振荡模式参数的变化。我们证明了两个安静区域之间的模式参数的差异可以像一对活跃和安静区域之间的差异一样大。这使我们得出结论,得出的结果的基础上,一个单一的安静的区域可能是有偏见的。

英文摘要:

We apply the ring-diagram technique to high resolution Dopplergrams in order to estimate the variation in oscillation mode parameters between active and quiet regions. We demonstrate that the difference in mode parameters between two quiet regions can be as large as those between a pair of active and quiet region. This leads us to conclude that the results derived on the basis of a single quiet region could be biased.
