• Final: Matter power spectrum (Ch 30) due noon Wed Dec 19.
  Power spectrum data downloadable from http://www.sdss3.org/science/boss_publications.php
  Look for data in
  Anderson_2013_CMASSDR11_power_spectrum_post_recon.dat
  and covariances in
  Anderson_2013_CMASSDR11_power_spectrum_post_recon_cov.dat
  You are welome to look for a more recent measurement — SDSS is currently in Data Release 15, or DR 15. I did not find anything more recent than DR11 in a conveniently summarized format.
