An Extreme-precision Radial-velocity Pipeline: First Radial Velocities from EXPRES [PDF]
The Astronomical Journal, 2020 The EXtreme-PREcision Spectrograph (EXPRES) is an environmentally stabilized, fiber-fed, R = 137,500, optical spectrograph. It was recently commissioned at the 4.3 m Lowell Discovery Telescope near Flagstaff, Arizona. The spectrograph was designed with a
