This page provides data products associated with the WiggleZ Dark Energy survey measurement of the galaxy power spectrum, described in axiv:1003.5721, Blake et al 2010, and arxiv:1210.2130, Parkinson et al 2012. We also make available a module for the Cosmological analysis code CosmoMC. We also make available the random catalogues used for the WiggleZ BAO measurement, as described in arxiv:1108.2635, Blake et al 2011.

If you have any questions regarding this data set, or associated module, please contact David Parkinson, d.parkinson [at] uq.edu.au.

Parameter constraints for WiggleZ combined with other data sets

Module

The CosmoMC module can be downloaded from here (this module works with the June 2013 version of CosmoMC. The previous module one can be found here). The module provides a slightly updated version of some of the source files for CosmoMC, and includes the details of the non-linear P(k) modelling needed to analyse the data up to to maximum wavenumber of k=0.2 h/Mpc.

Data

Power spectra (left) and covariance matrices (right) for the four redshift bins, averaged over the seven regions.

The WiggleZ Dark Energy survey measured the power spectrum in four redshift bins and seven regions on the sky, giving 28 separate power spectra in total. We make all of these available, including the window functions and covariance matrices. For ease of use, the power spectra for each redshift bin have been concatenated together in a single file.

The complete set of files (for the data alone) can be downloaded from here. The individual files are:

For the first redshift bin (0.1 < z < 0.3):
wigglez_nov11a_measurements.txt - the P(k) measurement in k-bins for each of the regions
wigglez_nov11a_cov.txt - the P(k) covariance matrix for each of the regions
wigglez_nov11a_windows.txt - the window function for each of the regions

For the second redshift bin (0.3 < z < 0.5):
wigglez_nov11b_measurements.txt - the P(k) measurement in k-bins for each of the regions
wigglez_nov11b_cov.txt - the P(k) covariance for each of the regions
wigglez_nov11b_windows.txt - the window function for each of the regions

For the third redshift bin (0.5 < z < 0.7):
wigglez_nov11c_measurements.txt - the P(k) measurement in k-bins for each of the regions
wigglez_nov11c_cov.txt - the P(k) covariance matrix for each of the regions
wigglez_nov11c_windows.txt - the window function for each of the regions

For the fourth redshift bin (0.7 < z < 0.9):
wigglez_jan11d_measurements.txt - the P(k) measurement in k-bins for each of the regions
wigglez_nov11d_cov.txt - the P(k) covariance matrix for each of the regions
wigglez_nov11d_windows.txt - the window function for each of the regions

For all the redshift bins:
wigglez_nov11_kbands.txt - the k-bins for which the power spectra has been measured. The same for all redshift bins.
