Planck Third Party Products

Data products created using Planck data, but not included as part of the official Planck Data Releases.

Planck Third Party Products
Name Release Date Description
Planck Polarized Synchrotron Revisited,
ADS		 2024 Products for full sky synchrotron emission polarization evaluated at a frequency of 30 GHz. The data is obtained by combining WMAP K, Ka and Q band with Planck LFI 30 GHz and 44 GHz observations, assuming a power law synchrotron emission scaling with frequency, with spectral index -3.1. Files include Stokes Q and U polarized synchrotron sky maps, E and B-mode harmonic space representation, as well as masks and simulation files. See README.txt for more information.
Planck CO Revisited,
ADS		 2024 Full-sky CO maps at 10’ angular resolution with low astrophysical contamination and significantly enhanced noise properties. A specific pipeline was designed to evaluate and postprocess the existing Planck Galactic CO maps and an extension of the Generalized Needlet Internal Linear Combination method was used to extract multi-component astrophysical emissions from the multi-frequency Planck observations. Final maps and noise simulations are provided, see README.md for more information.
Improved PR4 Compton-y SZ Map,
Maps (Direct download link),
Masks (Direct download link), ADS		 2023 All-sky Compton-y parameter map of the thermal Sunyaev-Zeldovich (SZ) effect from the Planck PR4 data, constructed using a tailored Needlet Internal Linear Combination (NILC) pipeline. For more details see Chandran, Remazeilles and Barreiro (2023).
CosmoGlobe DR1
CosmoGlobe, ADS		 2023 Joint analysis of WMAP (23, 33, 41, 61 and 94 GHz) and Planck LFI (30, 44, 70 GHz) time-ordered data, processed within a single Bayesian end-to-end framework using Commander. Data Release 1 (DR1) includes the reprocessed WMAP and LFI temperature and polarization maps, derived astrophysical components, and chains. All maps and the associated code are publicly available.
BeyondPlanck Global Bayesian Analysis (BP10)
BeyondPlanck, ADS		 2022 BP10 provides an updated reprocessing of Planck Low Frequency Instrument data (30, 44, and 70 GHz) from raw time-ordered observations, including joint determination of instrument, astrophysical, and cosmological parameters through Gibbs sampling. The main product is an ensemble of frequency sky map samples, each of which corresponds to one possible realization of the various modelled instrumental systematic corrections. Posterior mean maps are provided.

Reproduction of Planck 2018 results using Simons Observatory pipeline, ADS		 2021 Reproduction of Planck 2018 angular power spectra in temperature and polarization, and associated covariance matrices, using public Planck data products. Power spectra and LCDM cosmological parameters match the Planck versions to 10% of the statistical uncertainty or better. The code pipeline is available as part of the Simons Observatory PSpipe package, found here
BeyondPlanck Global Bayesian Analysis
BeyondPlanck Website, ADS		 2020 Reprocessing of Planck Low Frequency Instrument data (30, 44, and 70 GHz) from raw time-ordered observations, including joint determination of instrument, astrophysical, and cosmological parameters through Gibbs sampling. Also includes some external data sets such as WMAP. Released products include new full-sky maps at each frequency channel, estimates of polarized synchrotron emission, and likelihood code for large-scale CMB polarization analysis. The software necessary for the time-domain analysis is public under an Open Science license.
SRoll3.0 857 GHz Map
SRoll site, ADS		 2020 Intensity maps generated from Planck HFI 857 GHz observations using the SRoll 3.0 neural network based data inversion algorithm to reduce large-scale systematic effects. The algorithm predominantly targets reduction of far sidelobe pickup in the maps. The data release is comprised of individual 857 GHz detector maps for the full mission, the first half of the mission and the second half of the mission.
SRoll2.2 Maps
SRoll2 site 		2019 Intensity and polarization maps generated from Planck HFI observations at 100, 143, 217, 353, 545 and 857 GHz using version 2.2 of the SRoll destriping algorithm. This data release includes individual detector maps in addition to frequency maps. Changes compared to the SRoll2.0 algorithm and a caveat regarding the use of the SRoll2.2 maps are given on the SRoll site.
SRoll 2.0 Maps and Simulations
SRoll2 site, ADS		 2019 Intensity and polarization maps generated from Planck HFI observations at 100, 143, 217 and 353 GHz, using version 2.0 of the SRoll destriping algorithm. Version 2.0 products are intended to further reduce large-scale systematics not fully removed in the HFI legacy maps using the original SRoll algorithm. Simulations are also provided, along with a likelihood as described in Pagano et al. 2019.
Lenz et al. CIB Maps
ADS		 2019 Large-scale CIB maps of Lenz et al. 2019 formed from Planck HFI 353, 545, and 857 GHz intensity maps using an H I template method to remove foreground Galactic dust emission for approximately 25% of the sky. Other data products include CIB auto and cross power spectra and CIB-CMB lensing cross power spectra.
