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 ACS, WFPC2 and WFC3 images. The sources are detections based on combined images that are each for a particular filter, detector, and visit (Hubble Space Telescope (HST) pointing).
