Abstract: High fidelity iodine spectra provide the wavelength and instrument calibration needed to extract precise radial velocities (RVs) from stellar spectral observations taken through iodine cells. Such iodine spectra are usually taken by a Fourier Transform… read more here.

DOI: 10.1093/mnrasl/sly227
Abstract: The HIRES spectrograph belongs to a small group of radial-velocity (RV) instruments that produce stellar RVs with long-term precision down to $\sim1$ m/s. In $2017$, the HIRES team published $64,480$ RVs of $1,699$ stars, collected… read more here.
