The Ritter Observatory Public Archive of Spectra of ε Pegasi

Sample spectrum of the supergiant star ε Pegasi 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

A log of Ritter observations of ε Peg 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.

• The instrumentation
  
• The data reduction and the final data products archived here.
• Observing logs for the nights on which your spectra were taken. All nights of observation since 2004 November 6 (UT) are included.
