  SpectroWeb is an online maintained interactive graphical database of digital
spectral atlases of spectral standard stars at http://spectra.freeshell.org .
It is an efficient and user-friendly research tool for accurate analyses of
stellar spectra observed with large spectral resolution, including the solar
spectrum. The web-interface displays observed and theoretical stellar spectra,
and comprehensively provides detailed atomic and molecular line information via
user interaction. It fully integrates interactive spectrum visualization tools
for the analysis, management, and maintenance of large volumes of spectral
line-identification, -transition, and -property data. SpectroWeb 1.0 currently
offers optical (3300-6800 A) flux normalized high-resolution spectra of
Betelgeuse (M2), Arcturus (K1), The Sun (G2), Beta Aqr (G0), Procyon (F5), and
Canopus (F0). The provided line identifications are based on state of the art
spectrum synthesis calculations. The graphical database is under permanent
development as an online repository of identified (absorption) lines in
spectral standard reference stars, covering a broad range of stellar spectral
types. Its object-oriented (Java) implementation offers future expansion
capabilities to link and read stellar spectral atlases from various public
internet sites.
