Figure 8: Photometry and proper motions in the region of NGC 5385. a) Color-magnitude diagram. Open squares are Tycho 2 stars for which there are both proper motion and radial velocity measurements (see panel b) and Table 6), while filled triangles are stars having only proper motion measurements. b) Vector point plot of Tycho 2 proper motions and proper motion errors. Symbols are as in panel a). The identification numbers are from Tycho 2. See text for more details. |
