The discovery of the periodic planetary-like photometric signals for the four systems presented in this study were obtained from the images registered by the three stations of the HATSouth network (the HS1 and HS2 instruments in Chile, HS3 and HS4 in Namibia, and HS5 and HS6 in Australia). Observations were performed with a typical cadence of 5 minutes using a Sloan r photometric filter. The original images were reduced to photometric light curves by following the procedures described in Penev et al. (2013, J/AJ/145/5). Precision radial velocities are required to confirm the planetary nature of a transiting companion by providing the means to estimate its mass and orbital parameters. For this purpose, we used the FEROS spectrograph (Kaufer & Pasquini 1998SPIE.3355..844K) installed at the MPG 2.2 m telescope. HATS-43 and HATS-45 were observed with the HARPS instrument (Mayor et al. 2003Msngr.114...20M) mounted on the ESO 3.6 m telescope, which is located at the ESO La Silla Observatory. Finally, HATS-46 was observed with the Planet Finder Spectrograph (PFS; Crane et al. 2010SPIE.7735E..53C) mounted on the Magellan/Clay 6.5 m telescope at Las Campanas Observatory.(3 data files).
