Cleaning PPG data

[wchiaching6]

Hello NeuroKit Team:

I have a question about cleaning PPG data. I used nk.ppg_clean() to clean raw PPG, process with nk.ppg_process() and got the diagram with nk.ppg_plot(). In the diagram, I saw some abnormal heart rates (<50 or >150 bpm). I wonder if there are methods I can do to further refine the data. Thank you so much.
