Pierre Fernique, Thomas Boch, Anais Oberto, Francois-Xavier Pineau
TL;DR
The MocServer efficiently manages and queries large astronomical coverage datasets, providing rapid intersection results for any sky region, enhancing data accessibility for astronomers.
Contribution
It introduces a fast, standardized MOC-based server capable of handling extensive sky coverage data and delivering quick intersection queries.
Findings
Handles about 15,000 spatial footprints.
Provides intersection results in a few milliseconds.
Deployed and operational since June 2015.
Abstract
The MocServer is an astronomical service dedicated to the manipulation of data set coverages. This server sets together about 15 000 spatial footprints associated to catalogs, data bases and pixel surveys. Thanks to the Multi-Order Coverage map coding method (MOC1.0 IVOA standard), the MocServer is able to provide in a few milliseconds the list of data set identifiers intersecting any polygon on the sky. The MOC server has been deployed in June 2015 by the Centre de Donnees astronomiques de Strasbourg. It is operational and already in use by Aladin Desktop and Aladin Lite prototype versions.
