Scientific paper

We present our work on improving the radial velocity precision of the High Resolution Spectrograph (HRS) on Hobby-Eberly Telescope (HET). This stable, fiber-fed spectrograph had a reported RV precision of around 3-5 m/s. Upon HRS upgrades, combined with our improved procedures on spectral reduction and RV extraction, we have achieved 3m/s, and are pushing this limit towards 1m/s.
