Asteroids as radial velocity and resolving power standards for medium and high resolution spectroscopy

Asteroids as radial velocity and resolving power standards for medium and high resolution spectroscopy

Echelle spectra of 10 bright asteroids are presented and compared against an observed twilight spectrum and a computed Solar spectrum. Spectra covering a 2130 Å spectral range centered on Å are of high resolving power and high signal to noise ratio. We compare detailed properties of spectral lines and not …
