Notes. We list the effective temperatures, stellar masses and radii, planet-star separations, chromospheric activity indicator 
(from Knutson et al. 2010), pressure scale heights (HP), tidal heights (Ht), and ratio Ht/HP based on the formulae given by Cuntz et al. (2000). Stellar data are taken from the exoplanets.eu catalog and ordered by decreasing Ht/HP ratio. Data of WASP-19 are shown because of the planet-star separation very similar to WASP-18. WASP-18 is the only star with pressure scale height and tidal height of the same order of magnitude. The second highest Ht/HP ratio (~ 20%) is seen in WASP-12, which has low activity like WASP-18.
