vo@fai.kzspectroscopystars One-dimensional reduced optical stellar spectra obtained at the Three College Observatory (TCO) with the eShel spectrograph on the 0.81-m telescope. This collection includes the full supplied archive, including the stars in the separately published hot-supergiant subset and additional stellar targets. Wavelengths are computed from the original linear IRAF WCS in Angstroms and served in meters. Fluxes are relative; continuum normalization is recorded only where supplied in the metadata. Resolving power R=12000 is adopted from the existing collection documentation, not measured separately for each spectrum.https://dachs.fai.kz/tableinfo/tco_echelle_spectra.raw_dataArchiveResearchThree College ObservatoryeShel spectrographOpticaltco_echelle_spectra One-dimensional reduced optical stellar spectra obtained at the Three College Observatory (TCO) with the eShel spectrograph on the 0.81-m telescope.
