Top: spectral features of AT 2014ej including the Ca II H&K, Hβ, and Hα lines. The continuum of each spectrum was fit using a low-order polynomial and was subtracted from the data. The Lorentzian line profile fits are overplotted with a red line, and the corresponding line velocities are listed and also provided in Table 11. Bottom: MIKE spectrum around Hα in velocity space. The profile is well fit by two components consisting of a broad Lorentzian and a narrow P Cygni profile (sum of two Lorentzians with the same width) whose FWHMs are reported in the figure.
