Similar to near-Earth asteroids studies, observational surveys of the Kuiper Belt are faced with a variety of biases. (1) the inability of survey to see objects past their magnitude limit (flux bias), making the discovery of high-eccentricity objects less likely, but also low-eccentricity objects with large semimajor axes. (2) the tendency for surveys to be preferentially near the ecliptic, favoring the discovery of objects on low-inclination orbits. (3) the difficulty of tracking objects over several years, leading to the potential loss of objects with unusual orbits.
This talk will illustrate the use of the CFEPS survey simulator, which uses knowledge of the pointing history, tracking history, and sky conditions of the CFEPS survey (see preceding talk by Petit et al). We will compare a sequence of theoretical models to the L3 data release to eliminate some simple models and constrain the orbital distribution and relative population of various sub-components of the Kuiper Belt. In particular, we give (model dependent) constraints on the plutino fraction, size of the scattered disk, and relative populations of the inner and outer classical belts.
