Halpha data provide rough upper limits on the level of free-free emission in the data sets. The cross-correlation analysis does not contradict a two-component foreground emission hypothesis, with the two dust-correlated components being free-free emission and spinning-dust emission.en-USIn Copyrightcosmic microwave backgroundcosmology : observationsdiffuseradiationdust, extinctiondark-matter cosmogoniesspinning dust grainsh-alpha emissionmeasurement constraintssky mapsinfrared cirrustenerife dataradiationscalespowerGalactic Foregrounds in Owens Valley Radio Observatory and UCSB South Pole 1994 Cosmic Microwave Background Anisotropy DataArticle - Refereedhttp://iopscience.iop.org/0004-637X/579/1/83Astrophysical Journalhttps://doi.org/10.1086/342702
