室女团盘星系自转向量的分布Ⅰ.室女天区310个盘星系的表

Distribution of the Spin Vectors of the Disk Galaxies of the Virgo Cluster. Ⅰ. The Catalogue of 310 Disk Galaxies in the Virgo Area

为进一步研究室女星系团盘星系自转向量的分布,本文编制了该天区有UGC发表的方位角或直径数据的310个盘星系的表(81个S0系,229个S+Irr系),其中有UGC发表的方位角的星系为245个(67个S0系,178个S+Irr系)。对能证认身份的所有星系的星系云,群归属均已在表中注明。本文还讨论了表列星系的一些基本统计特征,为室女团盘系自转向量分布的研究提供了迄今为止可能是最大的,3组完整的代表性样品。

A catalogue of 310 disk galaxies(81 lenticulars, 229 spirals and Irregulars) with the UGC measured position angle and/or cliameters in the Virgo area has been compiled. Of them, 245 galaxies(67 SO and 178 S+Irr) have the values of UGC position angles. The respective memberships o/the galaxies of various clouds and groups are denoted in the taralogue. Some fundamental characteristics of our database have been discussed. Three sets of the representative samples of galaxies have been formed for the research of the distribution of spin vectors of the disk galaxies of the Virgo Icluster
