Each line corresponds to a different model in the search grid. The opacity is proportional to Akaike weights: darker lines are for more likely models (decreasing ΔAIC values), conversely, lighter lines are for gradually less probable models (increasing ΔAIC values). The spread of the lines provides an indication of the uncertainty of the recovered amplitude spectrum.
