This animation shows a GPI simulated data cube. Each frame represents a small step in wavelength. Note how one planet (lower left of the star) winks in and out of the animation, while the other (above the star) gets brighter very slowly. This is how GPI will deliver near-infrared spectra of exoplanets.
