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.
