We show that the set of Bragg peaks with high intensity is always Meyer (if it is relatively dense). We use this to provide a new characterization for Meyer sets in terms of positive and positive definite measures. Our results are based on a careful study of positive definite measures, which may be of interest in its own right.enAll Rights Reservedautocorrelationdiscrete Fourier transformBragg peakcompact abelian grouppure pointArticlehttps://doi.org/10.1007/s00023-015-0409-x
