The applications we have in mind are to the hadronic vacuum polarization that determines the most important hadronic correction $a_\\mu^{\\rm HVP}$ to the muon anomalous magnetic moment. First, we point out how spectral weights may be chosen that emphasize narrow regions in $\\sqrt{s}$, providing a tool to investigate emerging discrepancies between data-driven and lattice determinations of $a_\\mu^{\\rm HVP}$.
