| Abstract: |
We present a study on noise in space-based photometry originating from sensitivity variations within individual pixels, known as intra-pixel variations, and satellite attitude jitter. We have measured the intra-pixel structure on an e2v 47-20 CCD and made simulations of the effects these structure will have on the photometry obtained with the COROT satellite. By analyzing these simulations we are able to develop tools for lowering these effects, not only on COROT but for other space missions as well, e.g. Kepler. |
