This is a detailed spectral classification of 96 active galaxies from the Véron-Cetty and Véron catalog (2010, Version 13, VCV-13) of active galaxies and quasars. These objects were identified as radio sources using standard radio catalogs. Those galaxies which had radio sources in at least 6 different radio bands and had been identified spectrally in the SDSS catalog were selected. The types of activity of these were determined using their SDSS spectra. Three diagnostic diagrams and a direct study of the spectra were used for more certain classification. As a result, the classifications of 85% of the objects were changed. The radio sources in different radio bands make it possible to construct the spectral distribution of the energy in the radio range and to compare it with the optical activity types.

放射性星系样本的活动类型分类

这是活动星系和类星体的Véron-Cetty和Véron目录(2010年,第13版,VCV-13)中96个活动星系的详细光谱分类。使用标准无线电目录将这些对象识别为无线电源。选择那些具有至少6个不同无线电频带中的无线电源并且已在SDSS目录中进行光谱识别的星系。这些的活动类型使用其SDSS光谱确定。三个诊断图和对光谱的直接研究用于更确定的分类。结果,改变了85%的对象的分类。不同无线电频带中的无线电源可以构建无线电范围内能量的光谱分布,并将其与光学活动类型进行比较。
