VizieR Online Data Catalog: RV & light curves data for 4 G-type dwarf stars (Henning+, 2018)

The four stars were observed thousands of times by the HATSouth telescopes between 2010 March and 2013 July. The data concerning all photometric observations are available in electronic format in Table 4. Precise RV measurements of the targets were then acquired by using several medium- and large-class telescopes, equipped with high-resolution spectrographs and working on wide ranges of optical wavelengths. In particular, we mainly used the FEROS spectrograph (Kaufer & Pasquini 1998SPIE.3355..844K), which is mounted on the MPG 2.2 m telescope at the ESO Observatory in La Silla, for monitoring the four targets. Other spectra were collected thanks to CORALIE (Queloz et al. 2001Msngr.105....1Q) on the Euler 1.2 m telescope, HARPS (Mayor et al. 2003Msngr.114...20M) on the ESO 3.6 m telescope, which are also located at the La Silla observatory, and CYCLOPS mounted on the 3.9 m Anglo-Australian Telescope at SSO. For the case of HATS-50, which is the faintest star of the four (V=14.0 mag), we needed higher S/N measurements. These were obtained by taking seven spectra with the HIRES spectrograph (Vogt et al. 1994SPIE.2198..362V) on the Keck I 10 m telescope at Mauna Kea Observatory in Hawaii.
