头尾星系中最大结构的尺度大小还不为人所知。Vallee和Wilson（1976）先前对头尾星系IC 711的观测显示，它的尾巴延伸出光学星系13弧分，使其成为已知最长的头尾星系。利用彭蒂克顿的合成望远镜在74厘米的更长波长上进行的新观测表明，射电尾延伸得更远，至少达到17弧分，保持了它作为今天已知的最长头尾星系的地位。这些星系的起源的一些理论模型进行了讨论，特别是参考IC 711。21篇参考文献。
The scale size of the largest structure in head-tail galaxies is not well known. Previous observations of the head-tail galaxy IC 711 by Vallee and Wilson (1976) have shown its tail to extend 13 arcmin beyond the optical galaxy, making it the longest head-tail galaxy known. New observations at a longer wavelength of 74 cm with the synthesis telescope at Penticton show that the radio tail extends still further, to at least 17 arcmin, retaining its status as the longest head-tail galaxy known today. Some theoretical models for the origin of such galaxies are discussed with particular reference to IC 711. 21 references.
