PlanckRevised CO21 survey collection
Listed in IVOA Registry (Virtual Observatory)
The Planck space mission has observed the first three rotational lines of emission of Galactic carbon monoxide (CO).
Description
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.

These maps are made available to the scientific community and can be used to trace CO emission over the entire sky and to generate sky simulations in preparation for future cosmic microwave background (CMB) observations. Here is the Planck Revised CO 2-1 map.Original acknowledgement for data: We acknowledge the use of the Legacy Archive for Microwave
