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.

ACT DR6

• The Atacama Cosmology Telescope: DR6 Power Spectra, Likelihoods and ΛCDM Parameters, Louis et.al., 2025, ADS

CMB only spectra, binning_50
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 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.

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

POLARBEAR

• A measurement of the CMB E-mode angular power spectrum at subdegree scales from 670 square degrees of POLARBEAR data,
  Adachi et al. 2020, ADS
  

  The plotted bandpowers and uncertainties are from Table 1.

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.

SPT-3G D1

• SPT-3G D1: CMB temperature and polarization power spectra and cosmology from 2019 and 2020 observations of the SPT-3G Main field,
  Camphuis et al., 2025, ADS

  CMB only spectra

  The foreground- and nuisance-subtracted minimum-variance combination of the SPT-3G D1 multi-frequency band powers are
  provided for plotting purposes only, such as reproducing Figure 1 from Camphuis et al. (2025).

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.
