The Ritter Observatory Public Archive of Spectra of Normal A Stars

Sample spectrum of the Normal A star alpha CMa in the Hα region.

File names are in the form: observation date followed by serial number, followed by file extension .fits, as in YYYYMMDD.NNN.fits.

Unless otherwise noted, listed files are échelle spectra. The "IR region" ranges from 7910 to 9520 Å for échelle spectra; 8200 to 9100 Å for LDS spectra.
