IGRINS_RV: Radial velocity pipeline for IGRINS
Stahl, Asa G.; Tang, Shih-Yun; Johns-Krull, Christopher M.; Prato, L.; Llama, Joe; Mace, Gregory N.; Joon Lee, Jae; Oh, Heeyoung; Luna, Jessica; Jaffe, Daniel T.
IGRINS RV extracts radial velocities (RVs) from spectra taken with the Immersion GRating INfrared Spectrometer (IGRINS). It uses a modified forward modeling technique that leverages telluric absorption lines as a common-path wavelength calibrator. IGRINS RV achieves an RV precision in the H and K bands of around 25-30 m/s for narrow-line stars.
