Astro-WISE Information System
Astro-WISE is a scientific information system for the data processing of optical images. In this paper we review main features of Astro-WISE and describe the current status of the system.
متن کاملAstro-WISE and Grid
The paper reviews the Astro-WISE infrastructure and demonstrates that the Astro-WISE Information System provides a Grid itself. We describe the integration of Astro-WISE with an external Grid infrastructure (BiGGrid). The integration is performed on all infrastructural layers (data storage, metadata and processing layers) with Astro-WISE as a “master” infrastructure. We report the use of the in...
متن کاملMerging Grid Technologies Astro - WISE and EGEE
This paper studies the integration of the astronomical Grid solution realised in the Astro-WISE information system with the EGEE Grid and the porting of Astro-WISE applications on EGEE. We review the architecture of the Astro-WISE Grid, define the problems for the integration of the Grid infrastructures and our solution to these problems. We give examples of applications running on Astro-WISE a...
متن کاملSub-image data processing in Astro-WISE
Most often, astronomers are interested in a source (e.g., moving, variable, or extreme in some colour index) that lies on a few pixels of an image. However, the classical approach in astronomical data processing is the processing of the entire image or set of images even when the sole source of interest may exist on only a few pixels of one or a few images. This is because pipelines have been w...
متن کاملASTRO-WISE An Astronomical Wide-Field Imaging System for Europe
With the new one square degree high resolution wide field imagers coming on-line in the near future, such as the 268 Mpix OmegaCAM at ESO’s VST and the 360 Mpix MegaCAM at the CFHT, a new European-wide approach has been initiated to handle and disseminate the expected very large data volumes. For OmegaCAM both individual programs, including monitoring programs, and large sky survey programs are...
