The Ritter Observatory Public Archive of Spectra of α Leonis


Sample spectrum of the rapidly rotating hot star α Leonis 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 α Leo through March 2007 is to be found here. Additional information about each exposure is included.

Reprocessing is being done to correct a wavelength calibration error that is present in all spectra taken later than the fall 2002. Details.

A paper based, in part, on these spectra: 2008ApJ...682L.117G
