Caption: Figure 5.
Spectral time series of BP Tau around the C IV (left panels), He II (middle panels), and Mg II (right panels) lines. The top two rows correspond to the first epoch of observations (2021 August), while the bottom two rows were obtained in late 2022. The spectral time series are displayed as line plots showing flux variations color coded by days elapsed (top panels), and as images showing the line profiles variations with time (color coded by flux level).
