Using the HARPS spectrograph on the ESO 3.6-m telescope (La Silla, Chile), spectra of the planet host stars WASP-22 and WASP-26 were obtained through transits of their close-in planets, as well as across their orbits. The radial-velocity (RV) measurements extracted from the spectra are presented here. RVs were re-extracted from the six HARPS spectra of WASP-22 obtained by Maxted et al. (2010AJ....140.2007M) after removal of the instrumental blaze function (Triaud et al. 2010, Cat. J/A+A/524/A25) and are presented here.
Photometric transit observations of WASP-22 were obtained by the 0.6-m TRAPPIST and 1.2-m Euler telescopes (both at La Silla). A transit of WASP-26b was observed by the 0.35-m telescope at Oversky Observatory, La Palma. The Oversky data were originally made available at the Exoplanet Transit Database (http://var2.astro.cz/ETD/). The data are plotted in Figures 1 and 2.
