Notes. (†)Companions detected by AstraLux are also confidently detected with Gaia DR3, and their proper motions and distances point to them being physically bound to the main target. (††)The companions detected by AstraLux do not fully match the position of a nearby Gaia DR3 source that is likely physically bound to the main target. This can either be because the AstraLux detection corresponds to another source or because we are detecting the binary orbital motion of the Gaia source (see, e.g., the case of TOI-1450). (‡)Gaia DR3 source ID to which the source could potentially be associated.
