TL;DR: In this article, the spectral energy distribution (SED) of a blazar is modeled with a broken power-law spectrum, implying an additional emission component, and the spectral evolution of the high-energy-end of the optical-UV spectrum, revealed by the FUV observations in 2017 and 2018, strongly suggests that X-ray spectral changes in the normal broadband spectral state of OJ~287 are primarily due to the evolution of opticalUV synchrotron spectrum.
