TE and EE Power Spectrum Plot Data Sources

Here is a text file containing the data points used to generate the TE plot.

Here is a text file containing the data points used to generate the EE plot.


ACTPol

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

  • cmbonlyspectra.tgz

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

BICEP2+Keck

  • BICEP2/Keck Array VI: Improved Constraints On Cosmology and Foregrounds When Adding 95 GHz Data From Keck
    Array, Ade et.al. 2015, astro-ph

    BK_bandpowers_sample_20150129.txt
    The plotted bandpower error bars include statistical uncertainty and sample variance.

Planck

  • Planck 2015 results. XI. CMB power spectra, likelihoods, and robustness of parameters
    Planck Collaboration, et.al., 2016, A&A.., 594A, 11P
    ADS / astro-ph

    The data are available from the Planck Legacy Archive in the file COM_PowerSpect_CMB_R2.02.fits.

    Unbinned measurements are plotted at l < 30 and binned measurements are plotted at higher l.

    The EE measurements at l > 1500 are not included in the plot because their uncertainties are large.

SPTpol

  • Measurements of the Temperature and E-Mode Polarization of the CMB from 500 Square Degrees of SPTpol Data,
    Henning, J. W., et al., 2017, astro-ph

    bandpowers_sptpol_500deg2_TTEETE.txt

    The plotted bandpower error bars include sample and noise variance, and do not include calibration or beam uncertainty.

WMAP

  • Nine-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Final Maps and Results
    Bennett, C.L., et.al., 2013, ApJS., 208, 20B
    ADS / astro-ph

  • Nine-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Cosmology Results
    Hinshaw, G.F., et.al., 2013, ApJS., 208, 19H
    ADS / astro-ph

    wmap_binned_te_spectrum_9yr_v5.txt
    wmap_binned_ee_spectrum_9yr_v5.txt

    TE measurements for l > 600 and EE measurements for l > 200 are not included in the plots because their uncertainties are large.
