Gravitational Lensing Power Spectrum Plot Data Sources

lensing_data is a text file containing the data points used to generate the plots.


ACT 2013

  • The Atacama Cosmology Telescope: Temperature and Gravitational Lensing Power Spectrum Measurements from Three Seasons of Data
    Das, S. et al, 2014, JCAP.., 04, 014D
    ADS / astro-ph

    • Data from ACT_clpp_3yr_v1.dat in this tarfile
    As noted in the tarfile's readme.txt,the tabulated data are C_lkk.
    They were converted to C_lphiphi using C_lphiphi = 4 C_lkk / l4.

ACTpol 2016

  • The Atacama Cosmology Telescope: Two-Season ACTPol Lensing Power Spectrum
    Sherwin, Blake D., et.al.,
    astro-ph

    • The data plotted are from Table 1 or the file actPolS2_cls.txt in the lensing likelihood 2016 tarball

BICEP2/Keck 2016

  • BICEP2/Keck Array VIII: Measurement of gravitational lensing from large-scale B-mode polarization
    Keck Array, BICEP2 Collaborations,
    astro-ph

    • The data plotted are the BK14 auto-spectrum from Table 1

Planck 2018

  • Planck 2018 results. VIII. Gravitational lensing Planck Collaboration, et.al.,
    astro-ph
    Data from Table 1, combined temperature and polarization minimum-variance values for aggressive binning

POLARBEAR 2019

  • Measurement of the Cosmic Microwave Background Polarization Lensing Power Spectrum from Two Years of POLARBEAR Data, Aguilar Fa'undez et al. 2019, arXiv 1911.10980,
