This is Figure 3 of arXiv:1512.01216.

The upper panel shows the predicted measurement significance (model signal/instrument noise) in each frequency bin as well as its integral. The lower panel is the frequency integrated measurement with a shaded 1σ uncertainty limit along with the integrated cHN model spectrum. Both are normalized to the predicted model amplitude. The shaded region around the model curve is the 10% calibration uncertainty. The grey bands are frequencies vetoed using ancillary and housekeeping data.
