Also, of note the ica scale is off by quite a lot in the plot_sources plot, it is way too zoomed in.</div>

and when I skip all intermediate steps and just fit the ICA and apply it with an empty list for ica.exclude the signal still changes, quite a bit. I thought if no components were selected out and all the max PCA components were used the signal would be
unchanged or basically unchanged. Is this a bug or something with my implementation?</div>
