Optimization of multi-resolution observation strategies for cosmic microwave background experiments
Cosmic microwave background (CMB) observations are increasingly performed by using a combination of both small aperture telescopes (SATs) and large aperture telescopes (LATs) to extract information across a wide variety of angular scales. The observation strategy of the telescopes must balance the restrictions of the observing site, instrument constraints, and a variety of science goals. We present a general framework for simulating the performance of different observation strategies. Using this framework, we focus primarily on the inflationary science goal and determine the optimal LAT coverage for delensing SAT measurements and present a novel deep scan strategy for an experiment in Chile that improves observation efficiency in the deepest 3% of the sky by 26%. Finally, we present considerations for future surveys to consider to further increase their observing efficiency.
