Query: CMB reconstruction from the WMAP and Planck PR2 data   In this article, we describe a new estimate of the Cosmic Microwave
Background (CMB) intensity map reconstructed by a joint analysis of the full
Planck 2015 data (PR2) and WMAP nine-years. It provides more than a mere update
of the CMB map introduced in (Bobin et al. 2014b) since it benefits from an
improvement of the component separation method L-GMCA (Local-Generalized
Morphological Component Analysis) that allows the efficient separation of
correlated components (Bobin et al. 2015). Based on the most recent CMB data,
we further confirm previous results (Bobin et al. 2014b) showing that the
proposed CMB map estimate exhibits appealing characteristics for astrophysical
and cosmological applications: i) it is a full sky map that did not require any
inpainting or interpolation post-processing, ii) foreground contamination is
showed to be very low even on the galactic center, iii) it does not exhibit any
detectable trace of thermal SZ contamination. We show that its power spectrum
is in good agreement with the Planck PR2 official theoretical best-fit power
spectrum. Finally, following the principle of reproducible research, we provide
the codes to reproduce the L-GMCA, which makes it the only reproducible CMB
map.
