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
