Left: period-folded photometric measurements obtained with Spitzer/IRAC channel 1 (at 3.6 μm) near thetransits of the seven planets, corrected for the measured TTVs. Colored dots show the unbinned measurements; open circles depict the measurements binned over 5 min for visual clarity. The best-fit transit models are shown as dark blue lines. The numbers of transits that were observed to produce these combined curves are written on the plot. Right: similarly at 4.5 μm.
