Abstract

We present three full z-band transit light curves for the extrasolar planet XO-2 obtained with KeplerCam and the FLWO 1.2m telescope. The system parameters were determined fitting the data to transit models using a Markov Chain Monte Carlo simulation (MCMC). The main results presented in this poster are revised values for the parameters Rp/Rs, a/Rs and b.
