| Appendices | ||
| Nearly all the identifications of spectroscopic binaries in the target list are drawn from attributions in the 2015 Washington Double Star Notes file. After publication, the USNO astronomers informed me that the source (author) of these attributions, and the references used to compile them, are unknown. | ||
| 87 | remark for H V 17 | replace "#x2299;" with sol symbol |
