SpectroWeb 1.0 currently includes the complete optical spectrum of the Sun, Procyon, Epsilon Eridani, Arcturus, Canopus, Betelgeuse, and Beta Aqr with atomic, molecular, and Earth line identifications and detailed atomic data. When you select a star in the left-hand column and a spectral region of 10 or 25 Å, SpectroWeb will display the spectra and line identifications in this window by starting an interactive viewer. Once the viewer runs you can display all the spectra, list the spectral line identifications, with validated (and non-validated) atomic data and references. Use screen resolutions equal or larger than 1024x768 and maximize your browser for best viewing results.
