    Top: FORS1 R-band (red filled dots) and V-band (blue open dots) photometric data
    and fitted transit curves for OGLE-TR-10. The V-band data and fitted curve have been
    flipped across the transit central epoch for display.Bottom: Residuals to the fitted
    curves (R-band rms: 0.9 mmag, V-band rms: 0.7 mmag). From Pont et al. 2006.
