TCO Optical Echelle Spectral Archive

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.

This is queryData for the default operation; some services support getData as well
Only return the TOP "best" records (on this service, this usually is equivalent to MAXREC, so no ranking is implied).
