ary artifact components. By default, at least
    25% (`min_clean_fraction`) of the data must be clean EEG, and the rest
    can be contaminated. No more than 10% (`max_dropout_fraction`) of the
    data is allowed to come from contaminations that cause lower-than-EEG
    amplitudes (e.g., sensor unplugged). There are no restrictions on
    artifacts causing larger-than-EEG amplitudes, i.e., virtually anything is
    handled (with the exception of a very unlikely type of distribution that
    combines with
