The Ritter Observatory Public Archive of Spectra of ζ Ophiuchi


Sample spectrum of the rapidly rotating, sometimes Be star ζ Ophiuchi in the Hα region.

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

A log of Ritter observations of ζ Oph through March 2007 is to be found here. Additional information about each exposure is included.

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.
