This page provides data products associated with the SPTpol measurement of the CMB EE and TE polarization power spectra over 500 square degrees described in Chou et al., 2025. The power spectra are presented over the multipole range 50 < ell <= 8000 and can be used to constrain cosmological models using the likelihood package provided below.

If you have any questions regarding this data set or its use, please contact Jody T-L Chou (tlchou_at_uchicago_dot_edu).

Individual figures are available in PDF format here or bundled in a ZIP file here.

Below are links to FITS files containing 95 GHz and 150 GHz maps of the SPTpol 500d field from the full 2013-2016 season observations. Auxiliary files, instrument beams, and spectral bandpass functions are necessary for interpreting the maps. These files are included further below.

Maps:
Maps of the SPTpol 500d field in the 95 GHz and 150 GHz bands, presented in the oblique Lambert equal-area azimuthal projection.

Below are links to FITS files containing auxiliary information needed to interpret the SPT maps of the ra5h30dec-55 field observed in the 2008 season. These data products are described in detail in Schaffer et al. 2011, ApJ, 743, 90. Included below are pixel weight functions, noise PSD functions, and filter transfer functions for the two sets of maps provided in this release.

Weights:
Pixel weight functions for the maps presented above.

Filter Transfer Functions:
One-dimensional filter transfer functions appropriate for debiasing angular power spectra of the above maps.

Multipole-Space Beam Functions:
Azimuthally averaged spherical-harmonic-domain SPTpol beam functions for the 95 GHz and 150 GHz observing bands for the 2008 season.

Bandpass Functions:
Average SPT spectral bandpass functions for the 95 GHz and 150 GHz observing bands.

We provide the 95x95 GHz, 95x150 GHz, and 150x150 GHz TE and EE bandpowers from the full 2013-2016 SPTpol observations of the 500d field. The bandpowers cover the multipole range 50 < ell <= 8000 in bins of delta_ell = 50 between 51 < ell < 2000, delta_ell = 100 from 2001 < ell <= 3000, and delta_ell = 500 from 3001 < ell <= 8000.

Bandcenters, bandpowers, and bandpower errors for plotting are provided in a text file here. Bandpowers and uncertainties are given in D_ell units of uK^2. Each row is one ell-bin. The columns are (1) ell_min, (2) ell_max, ...

Note that these bandpowers include power from foregrounds, such as Galactic dust and point sources, though we do not significantly detect this power. Foreground terms are included in our likelihood model and priors for them may be adjusted by editing the accompanying SPTpol batch file provided in the likelihood package below.

If you have any questions regarding this data set or its use, please contact Jody T-L Chou (tlchou_at_uchicago_dot_edu).

Obviously change this text.
We provide files in a gzipped tarball here that can be added to the Nov16 version of CosmoMC to interface with the SPTpol EE and TE bandpowers discussed above. These files include the SPTpol likelihood, SPTpol data (bandpowers, covariance matrix, bandpower window functions, and beam error eigenvectors), batch file, and a README with instructions for how to compile CosmoMC with the SPTpol likelihood.

If you have any questions regarding the use of this likelihood, please contact Jody T-L Chou (tlchou_at_uchicago_dot_edu).
