TRAPPIST “I + z”-band and JGT R-band follow up high signal-to-noise photometry of WASP-56 during the transit (see Table 2). The JGT light curve has been offset from zero by an arbitrary amount for clarity. The The data are phase-folded on the ephemeris from Table 5. Superimposed (black-solid line) is our best-fit transit model estimated using the formalism from Mandel & Agol (2002). Residuals from the fit are displayed underneath.
