Table information for 'ztf.allwise'

General

Table Description:

AllWISE catalog entries for ZTF cross-matched sources, including WISE mid-infrared photometry (W1-W4 bands) and 2MASS near-infrared photometry (J, H, K).

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.
