class adam_core.observations.associations.Associations(table: Table, **kwargs: int | float | str)[source]¶

Bases: Table

detection_id¶: A column for storing large strings (over 2³¹ bytes long). Large string data is stored in variable-length chunks.

object_id¶: A column for storing large strings (over 2³¹ bytes long). Large string data is stored in variable-length chunks.

link_to_detections(detections: PointSourceDetections) → Linkage[Associations, PointSourceDetections][source]¶

Link the associations to a table of detections.

Parameters:: detections (~adam_core.observations.detections.PointSourceDetections) – Table of detections to link to.
