Table Description:
Gaia catalog cross-match properties for ZTF objects including distances and magnitudes of the nearest Gaia source and the nearest bright Gaia source.
This table is available for ADQL queries and through the TAP endpoint.
Resource Description:
Legacy ZTF astronomical catalog containing objects, detections, photometric measurements, classifications, and cross-matches from the Zwicky Transient Facility (ZTF) survey, as processed by the ALeRCE broker pipeline.
