VizieR Online Data Catalog: Optical photometry and RVs of TOI-481b and TOI-892b

Abstract

TOI-481 and TOI-892 were monitored by Transiting Exoplanet Survey Satellite (TESS) during its first year of operation. TOI-481 was observed in short-cadence (2minutes) mode in Sectors 6, 7, 9, 10, and 13, and in long-cadence (30minutes) mode in Sector 3. On the other hand, TOI-892 was only observed in Sector 6, in long-cadence mode.TOI-481 and TOI-892 were monitored with seven different spectrographs with the goal of measuring radial velocity variations to confirm the planetary nature of the transiting candidates and constrain their orbital parameters and masses. The Fiber-fed Extended Range Optical Spectrograph (FEROS) has a resolving power of R=48000 and is installed on the Max Planck Gesellschaft (MPG) 2.2 m telescope at La Silla Observatory in Chile. The CHIRON instrument is a high-resolution (R=80000) and fiber-fed spectrograph mounted on the 1.5m Smarts telescope at the Cerro Tololo Inter-American Observatory (CTIO), Chile. The Tillinghast Reflector Echelle Spectrograph (TRES) is a R=44000 fiber-fed instrument mounted on the 1.5m Tillinghast Reflector at the Fred L. Whipple Observatory (FLWO) on Mt. Hopkins, Arizona. CORALIE is a high-resolution (R=60000) fiber-fed spectrograph mounted on the 1.2m Swiss Euler telescope at La Silla Observatory, Chile. Minerva-Australis is an array of four PlaneWave CDK700 telescopes which can be simultaneously fiber-fed to a single KiwiSpec R4-100 high-resolution (R=80000) spectrograph. TOI-481 was monitored by Minerva-Australis using one and/or two telescopes in the array Minerva3 and Minerva4. Las Cumbres Observatory’s Network of Robotic Echelle Spectrographs (NRES) is a global array of echelle spectrographs mounted on 1 m telescopes, with a resolving power of R~53000.
