23. The range of k values that an observer is interested in searching for will depend on the availability of models predicting SGWBs with those values and the noise spectral profiles of the detector pair. The range chosen here is for illustrative purposes. However, the metric expression given here can be applied to estimate the required number of templates for a wider range of k values.
24. Note that the slow-roll inflationary SGWB spectrum will appear in the bandwidth of LISA- or LIGO-type detectors as a k ≈ 0 SPL spectrum, and will be indistinguishable from a BPL spectrum if either k- ≈ 0 and fp > f+ or k+ ≈ 0 and fp < f-. In this limited sense, the SRIM spectrum can be construed as a special case of the BPL.

27. All plots of the ambiguity function in this paper are computed numerically and give a more accurate, but not appreciably different, value of M(k, δk) than what can be estimated from Eq. (13).
