Abstract

We present an overview of the photometry simulation software developed for the Earth 2.0 (ET) mission. This software provides insights into the consequences of pre-production survey design choices by providing simulated pixel data required for photometric analysis. Validation of the simulation has been accomplished through comparison of simulated and real light curve data, reproducing Kepler’s light curves with combined photometric precision within 5 ppm of that measured in the real data. Large-scale noise component analysis on thousands of simulated stars is also in close agreement with those reported by the Kepler mission. Simulation results for ET show that the current design allows for a photometric precision of 34 ppm for 13th Kp magnitude solar-type stars when using a 6.5 hr integration.
