Description

V4 update: Fits file for the 2PCF multipoles have also been included

Description: Includes binned power spectrum multipoles and Gaussian covariance, to be used with cloelib/cloelike. Produced up to kmax = 0.4 h/Mpc with 100 linearly spaced bins (using the publicly available COMET code). Uses 4 redshift bins, from z=0.9 to z=1.8, with width of Delta_z=(0.2, 0.2, 0.2, 0.3) Both the synthetic data and the covariance were generated with the following parameters:

parameters = {
    'H0': 67.0,
    'Omega_cdm0': 0.27, 'Omega_b0': 0.049, 'Omega_k0': 0.0, 'mnu': 0.0,
    'w0': -1.0, 'wa': 0.0,
    'ns': 0.96, 'As': 2.1e-9,
    'gamma_MG': 0.545,
    'b1': np.array([1.412, 1.769, 2.039, 2.496]),
    'b2': np.array([0.695, 0.870, 1.162, 2.010]),
    'bG2': np.array([-0.156, -0.299, -0.400, -0.555]),
    'bGam3': np.array([0.323, 0.621, 0.827, 1.137]),
    'c0': np.array([30.948, 37.116, 36.738, 53.627]), (Mpc^2 units)
    'c2': np.array([46.233, 53.071, 48.626, 60.962]), (Mpc^2 units)
    'c4': np.array([10.057, 10.385, 8.643, 8.711]), (Mpc^2 units)
    'cnlo': np.array([0.0, 0.0, 0.0, 0.0]),
    'NP0': np.array([1.056, 1.152, 1.144, 1.309]),
    'NP20': np.array([0.0, 0.0, 0.0, 0.0]),
    'NP22': np.array([0.0, 0.0, 0.0, 0.0]),
    'fout': np.array([0.0, 0.0, 0.0, 0.0]),
    'sigmaz': np.array([0.0, 0.0, 0.0, 0.0])
}

The mixing matrices are just identity matrices. Additionally includes binned 2PCF multipoles, generated with the same set of parameters from smin=20 Mpc/h to smax=200 Mpc/h with a linear binning of 1 Mpc/h
