对Auer等人提出了改进意见。(1977)基于非线性最小二乘的斯托克斯剖面解析反演法。在Mueller吸收矩阵中引入附加物理(通过包括阻尼翼和磁光双折射，以及通过在分析中将强度分布与三向量偏振分布解耦)被发现导致了一种更稳健的反演方法，提供了更可靠和更准确的太阳黑子矢量磁场估计，而不会造成显著的经济损失。该方法被应用于用高海拔天文台偏振仪获得的太阳黑子观测。参考文献29篇。
Improvements are proposed for the Auer et al. (1977) method for the analytic inversion of Stokes profiles via nonlinear least squares. The introduction of additional physics into the Mueller absorption matrix (by including damping wings and magnetooptical birefringence, and by decoupling the intensity profile from the three-vector polarization profile in the analysis) is found to result in a more robust inversion method, providing more reliable and accurate estimates of sunspot vector magnetic fields without significant loss of economy. The method is applied to sunspot observations obtained with the High Altitude Observatory polarimeter. 29 references.
