Bedini L., Salerno E. Sampling the posterior density to estimate the CCA reconstruction error. Internal note, 2009.
In addition to what we have done in [2008-B4-007] and [2009-B4-001], we propose here another strategy to estimate the reconstruction error affecting the harmonic version of CCA. We sample the CCA posterior density by a Metropolis-Hastings algorithm to find the ridge densities for the synchrotron and the dust spectral indices. On this basis, the densities of the individual source cross-spectra components can also be estimated. A Matlab code to sample the spectral indices is included.
