Example of spectroscopic indicator time series analysis for J14524+123. Top: time series data with sinusoids corresponding to the best-fitting period (23.3 d) overplotted; Middle: time series of the individual indicators over the entire baseline; Bottom left: phase-folded on the strongest period; Bottom right: GLS periodogram (middle) and zoom-in on the strongest period (right) of the 4 indicators, with horizontal dashed line denoting FAP = 0.1% and the peak highlighted by the vertical line. Black = Hα, blue = Ca-IRTa, green = Ca-IRTb, magenta = TiO. Red denotes the window function.
