VizieR Online Data Catalog: TOI-1994 radial velocities with MINERVA & CHIRON (Page+, 2024)

TOI-1994b was spectroscopically observed by the MINERVA-Australis telescope array in Toowoomba, Australia at the University of Southern Queensland's Mount Kent Observatory. The telescopes T3, T4 and T5 were used for spectroscopic observations of TOI-1994. Each MINERVA-Australis telescope uses fiber optic cables to feed light into a spectrograph reaching resolution R=80000 for wavelengths from 480 to 630nm. A total of 47 spectra were taken by MINERVA-Australis between 2021 June 5 and 2021 July 12 with an exposure time of 3600s.

We also collected a 23 measurements with the CHIRON spectrograph on the 1.5m SMARTS telescope at CTIO in Chile. The observations were obtained between 2021 November 6 and 2022 May 1, resulting in full phase coverage for the orbit of TOI-1994b. We employed the fiber-fed image slicer to yield a resolving power of R~80000 between 4100 and 8700Å. The typical exposure time was 800s and resulted in a mean S/N per resolution element of 65.
