The Ritter Observatory Public Archive of Spectra of β Ophiuchi

Sample spectrum of the K-type giant β Ophiuchi 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

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.

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

As of March 7, 2013, this archive contains 257 spectra of this star. Right click on link to download desired file (individual spectra: 53 KB).
