Welcome to SpectroWeb 2.0, the interactive database of spectral standard star atlases. The SpectroWeb interface is an efficient tool for spectroscopists to identify detailed atomic and molecular features in astrophysical spectra. For more information about the current development status, news, and publications link to the SpectroWeb frontpages below.

SpectroWeb 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. You can display all the spectra, list the spectral line identifications with some atomic data. The viewer can be used for measuring equivalent width values of lines and features in the spectra. The results of your measurements can be saved to your local disk. You can also use this interface to load your own spectrum for comparison to the spectral standard star spectra and perform equivalent width measurements in your spectrum. The atomic database is currently under revision and will be updated with the atomic data compiled in the online BRASS repository.
