Sidelobe analysis for the Atacama Cosmology Telescope: a novel method for importing models in GRASP

Abstract
- Telescopes for observing the Cosmic Microwave Background (CMB) usually have shields and baffle structures in order to reduce the pickup from the ground. These structures may introduce unwanted sidelobes. We present a method to measure and model baffling structures of large aperture telescope optics to predict the sidelobe pattern.
