| 1 | the star has a resolved companion within 10000AU in the plane of the sky |
| 2 | bad broadening function solution |
| 4 | bimodal line profile likely indicative of spectroscopic binarity |
| 8 | RUWE>1.2, indicating likely unresolved binarity |
| 16 | RV recorded was ambiguously attributed to two components of a binary pair |
