This area is reserved for the archives of 2m telescope spectra that were made compatible with Virtual Observatory standards. Namely they use the Simple Spectrum Access Protocol (SSAP) to allow the VO-compatible clients easy search and download of spectra as well as seamless conversion of wavelength scale.
The archives have the classical web form interface allowing the search and preview of spectra of individual stars as well as some interactive postprocessing.
The main server engine behind all this is Pleinpot developped by P. Prugniel, CRAL
