Abstract

The Simons Observatory (SO) is a Cosmic Microwave Background experiment located in the Atacama Desert in Chile. SO consists of three small aperture telescopes (SATs) and one large aperture telescope (LAT) with a total of 60,000 detectors in six frequency bands.¹ As an observatory, SO encompasses hundreds of hardware components simultaneously running at different readout rates—all separate from its 60,000 detectors on-sky and their metadata. We provide an overview of commissioning SO’s data acquisition software system for SAT-MF1, the first SAT deployed to the Atacama site. Additionally, we share insights from deploying data access software for all four telescopes, detailing how performance limitations affected data loading and quality investigations, which led to site-compatible software improvements.
