SKYWALKER: Spitzer Key Yield With All that Light Kurve Exoplanet Research
The Spitzer Space Telescope Infrared Array Camera (IRAC) has a well known intrapixel effect in the 3.6 and 4.5 micron channels (Knutson et al 2008). This sub-pixel sensitivity variation manifests itself as several variations in the photometric flux measured that is dependent on the sub-pixel location of the PSF center. That is to say that the PSF walks along the sky and the flux read out varies as a result.
