1° resolution reconstruction at 30 GHz of (from left to right): synchrotron emission; free-free emission; AME; and thermal dust emission. These reconstructions are performed as described in Sect. 3.3.2. Rows from top to bottom: component amplitudes; noise rms; predicted rms of component separation error due to the estimation of AME and thermal dust spectra; and predicted rms of component separation error including a random error on β_s = −2.9 ± 0.1.
