GAVO & AstroGrid-D

GAVO Projects within the AstroGrid-D Goal: Develop example and standard procedures to combine the typical process of data reduction and processing, using the AstroGrid-D and GAVO tools & standards.

RAVE „Radial Velocity“ survey, collecting stellar spectra of 1 Mio local stars to measure radial velocity, metallicity and abundance ratios. Website running, data base growning continously. Currently only photometric data available. „Radial Velocity“ survey, collecting stellar spectra of 1 Mio local stars to measure radial velocity, metallicity and abundance ratios. Website running, data base growning continously. Currently only photometric data available. GAVO Projects: Necessary technical updates of already running VOTable webservice (switch to JDBC) Enlarge data base to include rave spectra: internally / for public use Decide about VO standard protocol for spectra: SDM („spectral data model“) versus SSA („simple spectrum access“) for RAVE data Use the AstroGrid-D to execute the RAVE data reduction pipeline Use synergy with the GAIA satellite project GAVO Projects: Necessary technical updates of already running VOTable webservice (switch to JDBC) Enlarge data base to include rave spectra: internally / for public use Decide about VO standard protocol for spectra: SDM („spectral data model“) versus SSA („simple spectrum access“) for RAVE data Use the AstroGrid-D to execute the RAVE data reduction pipeline Use synergy with the GAIA satellite project

Robotic Telescopes Automated data retrieval and storage of raw data Data reduction using the grid, reduced data stored in VO compliant data base Analyse and evaluate reduced data using VO tools RTML - RDF translation as first step for resource integration of RT into the Grid Develop interface to enable astronomer to easily specify new targets (for RT) using VO standards and tools Later: event-triggered observations with RT ( VOEvent ) Automated data retrieval and storage of raw data Data reduction using the grid, reduced data stored in VO compliant data base Analyse and evaluate reduced data using VO tools RTML - RDF translation as first step for resource integration of RT into the Grid Develop interface to enable astronomer to easily specify new targets (for RT) using VO standards and tools Later: event-triggered observations with RT ( VOEvent )

More Projects Implement simple data distribution methods for the common case of serialized data reduction using the grid Add simple access interfaces for VO compliant publishing of reduced data by individual astronomers Simplify publishing of single, ground based observations: Solar regions, spectra of bright stars. Increase amount of comparible data in these fields LOFAR: Solar Science Data Center at AIP GlowGrid: Event based observations with remote LOFAR stations Implement simple data distribution methods for the common case of serialized data reduction using the grid Add simple access interfaces for VO compliant publishing of reduced data by individual astronomers Simplify publishing of single, ground based observations: Solar regions, spectra of bright stars.
