Data products associated with the WiggleZ Dark Energy survey measurement of the Baryon Acoustic Oscillations (BAO), as described in Blake et al. arXiv:1108.2635 (2011, MNRAS, 418, 1707) Data is given for 6 WiggleZ regions (01, 03, 09, 11, 15, 22 hrs) in 3 different overlapping redshift slices (z=0.2-0.6, 0.4-0.8, 0.6-1.0), matching the datasets analyzed in the final WiggleZ baryon acoustic peak paper Blake et al. (2011, MNRAS, 418, 1707). For each sub-region the following files are given: Correlation function: xi_**hr*.dat - correlation function measurement and covariance matrix for each sub-region. Format of the file: 1st line: nbin, ngalaxy nbin lines: mean separation [Mpc/h], xi(s), sqrt[Cov(i,i)] nbin x nbin lines: i, j, Cov(i,j) The covariance matrix is from lognormal realizations, not jack-knife regions. Combined correlation function: xi_combined*.dat - correlation function measurement for each redshift range combining the measurements in each sub-region, in the same format as above. Integral constant: wigglez_ic.dat - integral constraint correction which should be added to the measured correlation function, format of the file is: Region [hr], zmin, zmax, integral constraint delta-xi We are considering adding another 90 random catalogues in the near future. For now the random catalogues used in the previous analysis are available below.
