ABSTRA C T观测到的太阳p模式频率提供了一个强大的诊断的内部结构的太阳,并允许我们测试在相当详细的物理学中使用的恒星结构理论。最常用的用于反演这种日震数据的技术是最优局部化平均值(奥拉)方法的两种实现,即减法最优局部化平均值(SOLA)和乘法最优局部化平均值(MOLA)。两者都是由一些参数控制的,这些参数的正确选择对于可靠地推断太阳能内部结构是非常重要的。在这里,我们做了详细的分析,每个参数对解决方案的影响,并指出如何达到一个最佳的参数设置为给定的数据集。
ABSTRA C T The observed solar p-mode frequencies provide a powerful diagnostic of the internal structure of the Sun and permit us to test in considerable detail the physics used in the theory of stellar structure. Among the most commonly used techniques for inverting such helioseismic data are two implementations of the optimally localized averages (OLA) method, namely the subtractive optimally localized averages (SOLA) and multiplicative optimally localized averages (MOLA). Both are controlled by a number of parameters, the proper choice of which is very important for a reliable inference of the solar internal structure. Here we make a detailed analysis of the influence of each parameter on the solution and indicate how to arrive at an optimal set of parameters for a given data set.
