CASSIS ARCHIVES This is the old CASSIS website. It is no longer updated but contains some information on the history of CASSIS. To get to the new CASSIS website click on the link below. Spectral data and web-based tools for the scientific analysis of high-resolution astrophysical spectra Emmanuel Caux, Alain Klotz, Adam Walters, Charlotte Vastel and Valerio Lattanzi Various data-bases regroup the latest spectral and collisional data from measurements and calculations. A variety of models (ranging from simple to highly complex) are available for different types of astrophysical object. Our idea is to create a web interface which will help a user to choose the most appropriate data and model to create a synthetic spectrum for the region to be studied. This CASSIS interface will also allow comparison of measured and calculated spectra and the adjustment of parameters for best correlation.       TEMPLATE for astrophysical objects Physical conditions : temperature, density, tec.   NO LONGER UPDATED               ASTROSPEC (review of spectroscopic data - new site)     Spectroscopic databases Spectra taken by telescopes   New CASSIS website     Spectral analysis programs       User Manual 1.1       Cassis Overview Collisional excitation e.g. Basecol Synthetic spectrum     People   Download Documentation   Links CESR     Contact : Adam.Walters@cesr.fr Web-based tools for the scientific analysis of high-resolution astrophysical spectra
