目标。本工作的目的是分析的可靠性推断的磁场强度从630 nm的Fe I线对在互联网安静的太阳区域。方法.已经进行了一些数值实验，证明这些线无法恢复在这样的低通量太阳区域的磁场强度。结果它示出了如何不同的模型大气，磁场强度范围从几百高斯到千高斯，引起斯托克斯配置文件，无法区分。这种简并的原因进行了讨论。
Aims. The purpose of this work is to analyze the reliability of the magnetic field strengths inferred from the 630 nm pair of Fe I lines in internetwork quiet Sun regions. Methods. Some numerical experiments have been performed that demonstrate the inability of these lines to recover the magnetic field strength in such low flux solar regions. Results. It is shown how different model atmospheres, with magnetic field strengths ranging from a few hundred Gauss to kiloGauss, give rise to Stokes profiles that cannot be distinguished. The reasons for this degeneracy are discussed.
