VIPERS Data Release Access

• Dedicated Web site
• http://vipers.inaf.it
• Exploiting DART

–

Present Web interface used by VIPERS team

–

Provides a simplified interface to perform queries to the catalogs and retrieve the data products related to the objects selected with the query

–

• L. Paioro, L. Chiappetti, B. Garilli, P. Franzetti, M. Fumana, M. Scodeggio:

DART, a New Solution to Deploy and Access Astronomical Data, 2008, ASPCS 394, 397- 399.

• Virtual Observatory protocols
• Catalogs: ConeSearch and TAP
• 1D Spectra: SSAP

–

Maybe work duplicated with ESO

• 2D Spectra?
• Ancillary data products?
