The present study investigates the telluric spectrum in the wavelength region surrounding the D1 and D2 lines of sodium. From spectrograms at high spectral resolution, detailed measurements were made of 222 lines, mostly identified as being due to atmospheric water vapor. From spectrograms with a high signal-to-noise ratio and strong telluric and faint or absent stellar and interstellar lines, a synthetic spectrum of telluric lines from 586.9 nm to 591.7 nm is constructed. Individual line positions for stronger telluric lines are accurate to about 7 x 10 exp -5 nm, corresponding to a radial-velocity precision of about 40 m/s. Individual relative equivalent widths for the same lines are accurate to about 7 percent. The present synthetic relative telluric spectrum can thus be converted into an absolute spectrum, reproduced to rather high accuracy. It is shown that use of the telluric spectrum is excellent for the purpose of high-precision radial velocities.
