Empirical model of transient plus stellar emission fit to the X-shooter and MUSE spectra for measuring the stellar kinematics in the wavelength range of the strong Ca ii H+K doublet, Hδ, Hγ, and the G band. The emission from the transient is clearly evident through the decrease in flux between 2016 and 2017, and a continuum that is substantially bluer than what would be expected from the Gyr-old stellar population (Sect. 3.3) of the host galaxy alone.
