I ought to have paid a little more attention to the plot.  HOPS gives you Rp/R* – in this case 0.149 +0.004/-0.005. 

According to SINBAD the stellar radius of WASP-2A is 0.821 +/- 0.013 RSun.

Using these data I get a mean value for WASP-2b of Rp=1.22Rj, with an upper limit Rp=1.27Rj and a lower limit Rp=1.16Rj. 

Seems I was a little closer to the accepted value by eye-balling the lightcurve.

Best regards
