Views along the 𝑦 , 𝑦 axes (a) and 𝑧 , 𝑧 axes (b) of reference systems 𝑆 and 𝑆 , which have parallel axes, that are fixed relative to the distant stars. The origin of 𝑆 is at earth's center, and the origins of 𝑆 and 𝑆 are at the pendulum suspension point. The local lab system 𝑆 has the 𝑧 axis vertical, the 𝑥 axis southward, and the 𝑦 axis eastward.
