Southern binary galaxies radial velocities

We present spectrophotometry of a sample of 26 Southern binary galaxies. 17 pairs were confirmed to be physically associated with typical separation of 136h^-1^kpc. Pairs with...本研究针对26个南天双星系样本开展了分光光度测量（spectrophotometry）。其中17对星系对被证实为物理成协系统，典型间距为136ℎ⁻¹千秒差距（kpc）。具有……的星系对
