Hubble Source Catalog Search Help

This page describes how to use the Hubble Source Catalog Search form and describes the individual fields in that form.

Use this form to search the Hubble Source Catalog by object name, position, and Detection level. Other fields can also be searched using the "user-specified field" options. The Hubble Source Catalog contains information about sources detected in many of the WFPC2 and ACS images. The sources are detections based on combined images that are each for a particular filter, detector, and visit (Hubble Space Telescope (HST) pointing).

Please visit our Use Cases for step by step instructions.

Please visit our FAQ page for additional information.
