BAO detection using the BAO wavelet with different radii (r BAO) and widths (s BAO). The top panel of this figure shows the average values of the differences in the detection coefficient B r,s between the BAO and no-BAO simulations weighted by the variance. The vertical green line is the expected BAO radius in the mocks. The middle panel shows the average over the variance for only the no-BAO simulations. The bottom panel shows the same applied to the data. In all cases, the contours simply follow the color map, where the solid contour corresponds to a value of zero while the dashed (dotted) lines correspond to positive (negative) 0.5σ and 1.0σ values. Dashed lines/red regions hence indicate values of the wavelet parameters with stronger BAO-like features. Finally, the green cross in the bottom panel indicates the wavelet parameters with the single largest BAO weight W r,s , which coincides closely with the center, width, and radius of Ho’oleilana derived via other means.
