TT Power Spectrum Plot Data Sources

TT Power Spectrum is a text file containing the data points used to generate the plots.


  • The Atacama Cosmology Telescope: A Measurement of the Cosmic Microwave Background Power Spectra at 98 and 150 GHz,
    Choi et al. 2020, ADS

    CMB only spectra

    CMB-only bandpowers, marginalized over astrophysical foregrounds. These spectra are released for plotting purposes and do not include the full covariance.


  • Planck 2018 results. VI. Cosmological parameters, Planck Collaboration, astro-ph

    Unbinned measurements available from the Planck Legacy archive are plotted at l < 30,
    and binned measurements provided to LAMBDA by the Planck team are plotted at higher l.
