In this article, we describe a new estimate of the Cosmic MicrowaveBackground (CMB) intensity map reconstructed by a joint analysis of the fullPlanck 2015 data (PR2) and WMAP nine-years. It provides more than a mere updateof the CMB map introduced in (Bobin et al. 2014b) since it benefits from animprovement of the component separation method L-GMCA (Local-GeneralizedMorphological Component Analysis) that allows the efficient separation ofcorrelated components (Bobin et al. 2015). Based on the most recent CMB data,we further confirm previous results (Bobin et al. 2014b) showing that theproposed CMB map estimate exhibits appealing characteristics for astrophysicaland cosmological applications: i) it is a full sky map that did not require anyinpainting or interpolation post-processing, ii) foreground contamination isshowed to be very low even on the galactic center, iii) it does not exhibit anydetectable trace of thermal SZ contamination. We show that its power spectrumis in good agreement with the Planck PR2 official theoretical best-fit powerspectrum. Finally, following the principle of reproducible research, we providethe codes to reproduce the L-GMCA, which makes it the only reproducible CMBmap.
