SEDs for the sources with very significant AME and . Data points are shown as circles with errors and are colour-coded for radio data (light blue), WMAP (red), Planck (blue), and DIRBE/ IRAS (black). The best-fitting model of free-free (dotted line), thermal dust (short-dashed line), CMB (triple-dot dashed line), and spinning dust (dot-dashed line) is shown. Data included in the fit are shown as filled circles, while the other data are unfilled. The residual spectrum, after subtraction of free-free, synchrotron, CMB, and thermal dust components, is shown in the insert. The best-fitting spinning dust model is also shown.
