Quaia data products for cosmolgy analysis

<p>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 <em>Planck</em> (<a href="https://arxiv.org/abs/2306.17748">Alonso et al. 2023</a>).</p> <p>The files included are:</p> <ul> <li><strong>cls_quaia_planckPR4_s8.fits</strong>: 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 <a href="https://github.com/damonge/quaia-cosmo-s8/blob/main/notebooks/CellReading.ipynb">here</a>.</li> <li><strong>selection_function_NSIDE64_G20.5_zsplit2binX.fits</strong>: the selection function map for bin X (0 and 1 for the Low-z and High-z bins used in the analysis, respectively), in <a href="https://healpix.jpl.nasa.gov/">HEALPix</a> projection with N_side=64.</li> </ul> <p>To reproduce the power spectra used in the analysis, you will need to combine the selection functions above with the public <a href="https://zenodo.org/record/8060755">Quaia catalog</a>, and the PR4 CMB lensing maps from the <a href="https://pla.esac.esa.int">Planck legacy archive</a>.</p>
