摘要
本文继(Ⅰ)文之后分析了六条多通道滤光器太阳磁场望远镜所用谱线在通过五种不同带宽滤光器后形成深度的变化规律,计算了距线心确定点处相对于最窄和最宽滤光器带宽的形成深度的均方差,从而总结出了所计算的正常及反常Zeeman线形成深度在通过不同带宽滤光器后的总体特征。 而通过计算在适当范围内,距线心各点处stokes参量V对磁场的反响,则确定出了对应于各谱线滤光器放置的最佳位置。再比较最佳位置上对应于最宽和最窄滤光器带宽的灵敏度确定出了最佳滤光器带宽。
The changes of the formation depth of 6 FeI lines, used by Multichannel Birefringence Filter Solar Magnetic Field Telescope, are studied in succeeding of paper [1] when they come through the equipment. The mean sqare root errors at the certain points from the line-center, corresponding to the narrowest and the widest bandwidth of the filter, are computed. Hence general properties of the formation depth of the normal and anormalous Zeeman lines passing through the multichannel filter, are summarized.
The best place for the filter to be set from the line-center in an appropriate area, are obtained by computing the magnetic field response of Stokes V parameter.Then comparing the sensitivities at the best places from the line-center with respect to the narrowest and the widest filter bandwidth of the filter, we have finally found out the best bandwidth of the filter.
