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: Two-Season ACTPol Spectra and Parameters
    Louis, Thibaut, et.al.,

    The plotted data are from the ACTPol two season data release.
    These replace the 3-year ACT data shown in a previous version of the plot,
    which are still available here.


  • 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.
