CU8 general activity around stars.
The DPAC CU8 activity is focus on the extraction of Astrophysical Parameters of the Sources that Gaia will observed. It consists in several independent modules using the data of the three instruments: Astrometric, Photometric and spectrometric. The sources will be classified in main three groups: QSOs, galaxies, stars. Most of the activity of CU8 is centralized on the quantitative parametrization of the stars single either multiple.
That activity of classification and characterization of the sources needs numerous synthetic spectra regrouped in libraries, these are used for the training of the algorithms developed in the CU2, CU6, CU8 of DPAC.
