COSI employs a compact Compton telescope design utilizing 12 high-purity cross strip germanium detectors (size: $8\\times8\\times1.5$ cm$^3$, 2 mm strip pitch).\n  We require well-benchmarked simulations to simulate the full instrument response used for data analysis, to optimize our analysis algorithms, and to bet","authors_text":"Alex Lowell, Andreas Zoglauer, Carolyn A.
