We present the new version of Spectrum Services for the Virtual Observatory. The two year long development period led to a reconsidered user interface, more available datasets, and several scientific functions. Currently available datasets include observed spectrum catalogs (SDSS DR1-DR4, 2dF), as well as simulated or theoretical catalogs (such as Charlot 100k spectrum library, BaSeL stellar library).
Newly available scientific functions include generation of composite spectra, dereddening and calculation of synthetic magnitudes convolving with band pass curves of optical instrument filters to generate simulated photometric catalogs on-the-fly. The most important services are the continuum and spectral line fitting functions which are available for the researchers through the web user interface and through the SOAP web services programmatically. When fitting continuum, different template sets can be chosen including Bruzual-Charlot '03 templates or the SDSS 450k eigenspectra).
MySpectrum is a cross-platform version of the spectrum web service for setting up your own spectrum repository. It integrates into the main service allowing easy access for the VO community to your data.
