PlanckRevised CO10 survey collection

Those maps, however, are either noisy or contaminated by astrophysical emissions from different origin. We revisit those data products to deliver new full-sky CO maps with low astrophysical contamination and significantly enhanced noise properties.

To that effect, a specific pipeline is designed to evaluate and postprocess the existing Planck Galactic CO maps. Specifically, we use an extension of the generalized needlet Internal Linear Combination method to extract multicomponent astrophysical emissions from multifrequency observations. Well-characterized, clean, CO full-sky maps at 10' angular resolution are produced.
