TT Power Spectrum Plot Data Sources

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


ACTpol

  • The Atacama Cosmology Telescope: Two-Season ACTPol Spectra and Parameters
    Louis, Thibaut, et.al.,
    astro-ph

    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

  • Planck 2015 results. XI. CMB power spectra, likelihoods, and robustness of parameters
    Planck Collaboration, et.al.,
    astro-ph

    The data for l < 30 are CMB bandpowers from the Commander component separation algorithm, available from the Planck Legacy Archive in the file COM_PowerSpect_CMB-TT-loL-full_R2.02.txt.

    The data for l > 30 are CMB bandpowers from the 'plik_lite' version of the Planck likelihood, available from the Planck Legacy Archive in the tar file COM_Likelihood_Data-baseline_R2.00.tar.gz at plc_2.0/hi_l/plik_lite/plik_lite_v18_TT.clik/clik/lkl_0/_external/cl_cmb_plik_v18.dat.
