摘要
我们于1986年9月30日在日本乘鞍日冕站使用口径25厘米的折轴日冕仪与其所属的摄谱仪拍摄了CaⅡ Hλ3968、FeⅠλ5250和FeⅠλ6303邻近的光谱。分析了这些资料。我们得到:1.光斑的连续反衬度和临边昏暗因子;2.FeⅠλ5250、FeⅠλ6301.5、FeⅠλ6302.5三条线的剩余强度和半峰全宽(FWHM)。
We observed the spectrum of solar photospheric faculae in Call H λ3968A, FeI λ 5250 A and λ 6303 A with the 25cm coronagraph at the Norikura Solar Observatory, Japan on 30 Sept., 1986.Analysing these data, we obtained: 1. the continuum contract and limb darkening factor of the faculae; 2. the residual intensity and FWHM of three lines (PeI λ 5250.25 A, λ 6301.5 A and λ 6302.5 A).
