vo@fai.kzspectroscopystars Extracted, wavelength-calibrated, unmerged stellar echelle spectra from the eShel spectrograph on the Zeiss-1000 telescope at Assy-Turgen Observatory. Each archive record delivers one original IRAF multispec FITS containing all extracted orders. Wavelength solutions are recorded separately for each order in the WAT2 header cards, in Angstroms. Orders are neither flattened nor merged. Downloaded files retain their original bytes. Wavelength bounds enclose all orders; they do not imply continuous coverage. Exposure duration is taken from EXPTIME. Flux calibration and resolving power are not established by these headers and are not assumed. Generic single-array spectrum viewers may not support IRAF multispec.https://dachs.fai.kz/tableinfo/fai_echelle_spectra.dataArchiveResearchIsServedByFAI archives ObscoreAssy-Turgen ObservatoryeShel spectrograph; Zeiss-1000OpticalivoaDefinition and support code for the ObsCore data model and table.ivoa.obscoreThis data collection is queryable in FAI archives's obscore table.fai_echelle_spectra Extracted, wavelength-calibrated, unmerged stellar echelle spectra from the eShel spectrograph on the Zeiss-1000 telescope at Assy-Turgen Observatory.
