Detailed Description

A collection of star cutouts.

Parameters
----------
candidates : `Iterable` [`ExtendedPsfCandidate`]
    Collection of `ExtendedPsfCandidate` instances.
metadata : `dict` [`str`, `MetadataValue`], optional
    Global metadata associated with the collection.

Attributes
----------
metadata : `dict` [`str`, `MetadataValue`]
    Global metadata associated with the collection.
ref_id_map : `dict` [`int`, `ExtendedPsfCandidate`]
    A mapping from reference IDs to `ExtendedPsfCandidate` objects.
    Only includes candidates with valid reference IDs.
