The Ritter Observatory Public Archive of Spectra of Normal KM Stars

Sample échelle spectrum of the K giant α Serpentis in the Hα region.

Sample LDS spectrum of the BY Dra-type variable YY Gem.

These spectra have been subjected to normal spectroscopic data processing, namely bias subtraction, flat fielding, extraction, and wavelength calibration. Before you use the data for science, we strongly recommend that you read the image headers and consult the following information.

File names are in the form: observation date followed by serial number, followed by file extension .fits, as in YYYYMMDD.NNN.fits. Right click on link to download desired file.
