Chandra Footprint Service: Visualizing Chandra's Sky Coverage

Watry, Aaron

The Chandra Footprint Service provides a visual interface to observational data in the public Chandra Data Archive and the Chandra Source Catalog. Users of the service are given the ability to directly see which areas of the sky have been observed by the Chandra X-Ray Observatory for any target of interest. The browser-based interface provides visualization of the sky coverage of Chandra instruments for any region of the sky along with tabular data for observations. The service provides an interactive client-based overlay of the instrument region data on top of a Sloan Digital Sky Survey background image, previews of observation images, access to data products, and access to the VOTable data used to create the interface. This work presents the interface and capabilities of the service and the technologies that make it possible.
