RAVERAVE
„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

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 ProjectsMore 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

MetaData-DescriptionE3D-data are stored in FITS-Format
Fits contains a WCS-description suitable for VO-Table COOSYS-Array
Problem: WCS in the fits-file
refers to the AG, ie the Telescope, not to the objects in the cube
Problem: the IFU normally have different characteristics, those are (afaik) not stored in the E3D-format
E3D-fits-files are supposed to have instrument-characteristics removed via processing the raw data
Still to be defined: error-margins for processed data

MetaData & VOTable-Conversion(aside of WCS-issue):
VOTable has no notion of spaxels standard conversion tool for FITS-Header
to VOTable-Header (aka MetaData) still missing
Standard set of MetaData for E3D to be defined
E3D-fits-file can be included into VOTable as a binary-tag (Is this what is desired?)
