Description

The files below contain the data that were used in the cosmological analysis of the Gaia-unWISE quasar catalog (Quaia) in combination with CMB lensing data from Planck (Alonso et al. 2023).

The files included are:

  • cls_quaia_planckPR4_s8.fits: the complete set of power spectra and associated metadata (covariance matrix, redshift distributions) needed to reproduce the fiducial analysis of the paper. The file uses the sacc format. A short notebook showing how to interpret the data can be found here.
  • selection_function_NSIDE64_G20.5_zsplit2binX.fits: the selection function map for bin X (0 and 1 for the Low-z and High-z bins used in the analysis, respectively), in HEALPix projection with Nside=64.

To reproduce the power spectra used in the analysis, you will need to combine the selection functions above with the public Quaia catalog, and the PR4 CMB lensing maps from the Planck legacy archive.
