VizieR Online Data Catalog: WASP-31b: a low-density planet transiting a metal-poor, late-F-type dwarf star.

The host star WASP-31 was observed by WASP-South during 2006 to 2011. The WASP photometry was corrected for blending with a star 4.1mag fainter, located 35 arcsec away. Spectroscopic measurements were obtained using the CORALIE spectrograph mounted on the Euler-Swiss 1.2-m telescope (La Silla, Chile) and the HARPS spectrograph mounted on the ESO 3.6-m telescope (La Silla, Chile) to confirm the planetary nature of the eclipsing body and to measure its mass. A total of 47 measurements were obtained by CORALIE, 1 of which fell during transit, and 10 measurements were obtained by HARPS. The data are plotted in Figures 1, 2 and 3.
