P. de Bernardis coauthored maps of <cosmic microwave background> temperature variations at four observing <frequencies>. Their angular <power spectrum> peaked near multipole $\ell=197\pm6$, supporting a spatially flat cosmological model within the paper's <cold dark matter> interpretation.<A Flat Universe from High-Resolution Maps of the Cosmic Microwave Background Radiation by P. de Bernardis and others>[Author list and abstract, corresponding to Nature 404 (2000), pp. 955–959: four-frequency maps, peak multipole and qualified flat-universe interpretation.]{ref}
