Images of 10 galaxies in F814W and F606W filters obtained on the Hubble Space Telescope (HST) are used to construct color-magnitude diagrams for the star population of these galaxies. The distances to the galaxies are estimated from the luminosity of the tip of the red giant branch. The galaxies examined here have radial velocities from 250 to 760 km/s relative to the centroid of the Local Group and distances ranging from 3.7 to 13.0 Mpc. Several other observed galaxies with low radial velocities are noted at distances beyond the limit of 13 Mpc.

哈勃太空望远镜观测到的10个附近星系的距离

在哈勃太空望远镜 (HST) 上获得的 F814W 和 F606W 滤光片中的 10 个星系图像用于构建这些星系的恒星群的颜色-星等图。到星系的距离是根据红巨星分支尖端的光度来估计的。这里检查的星系相对于本星系群质心的径向速度为 250 至 760 公里/秒,距离为 3.7 至 13.0 Mpc。在超过 13 Mpc 限制的距离处注意到其他几个观察到的具有低径向速度的星系。
