The computer program magreg in IDL language has been developed for determining the longitudinal component Bz of the magnetic field of stars. The program has been tested on observations of a number of objects at the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAN) using the main stellar spectrograph of the 6-m telescope. The well studied magnetic star γ Equ is used as an example of detailed analysis of observational data recorded for this object on August 29, 2015. The results are compared with published sources. Our next task is to analyze the entire observational data set of spectropolarimetric observations of γ Equ on the 6-m telescope at SAO in order to obtain a most uniform set of estimates of the parameter Bz.

从光谱极化观测确定恒星磁场纵向分量的程序Magreg

IDL 语言的计算机程序 magreg 已被开发用于确定恒星磁场的纵向分量 Bz。该程序已在俄罗斯科学院特殊天体物理天文台 (SAO RAN) 使用 6 米望远镜的主恒星​​光谱仪对许多物体的观测进行了测试。2015 年 8 月 29 日，该天体记录的观测数据以经过充分研究的磁星 γ Equ 为例进行了详细分析。将结果与已发表的资料进行了比较。我们的下一个任务是在 SAO 的 6 米望远镜上分析 γ Equ 的整个光谱偏振观测数据集，以获得参数 Bz 的最统一估计集。
