资源简介:

Includes binned C_ells, (binned identity) mixing matrix and Gaussian covariance for 3x2, to be used with cloelib/cloelike. Produced up to ell max = 5000 and with 32 ell bins. Uses 6 redshift bins with the n(z) from the other record on Zenodo. Both the synthetic data and the covariance were generated with the following 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, 'log10TAGN': 7.75, 'AIA':0.16, 'EtaIA':1.66, 'b1_photo_poly0': 1.33291, 'b1_photo_poly1': -0.72414, 'b1_photo_poly2': 1.0183, 'b1_photo_poly3': -0.14913, 'magnification_bias_1': 0.0, 'magnification_bias_2': 0.0, 'magnification_bias_3': 0.0, 'magnification_bias_4': 0.0, 'magnification_bias_5': 0.0, 'magnification_bias_6': 0.0, 'dz_pos_1': 0.0, 'dz_pos_2': 0.0, 'dz_pos_3': 0.0, 'dz_pos_4': 0.0, 'dz_pos_5': 0.0, 'dz_pos_6': 0.0, 'multiplicative_bias_1': 0.0, 'multiplicative_bias_2': 0.0, 'multiplicative_bias_3': 0.0, 'multiplicative_bias_4': 0.0, 'multiplicative_bias_5': 0.0, 'multiplicative_bias_6': 0.0, 'dz_shear_1': 0.0, 'dz_shear_2': 0.0, 'dz_shear_3': 0.0, 'dz_shear_4': 0.0, 'dz_shear_5': 0.0, 'dz_shear_6': 0.0,

本数据集包含分箱后的角功率谱C_ells、(分箱身份)混合矩阵,以及适用于3×2配置的高斯协方差矩阵,可与cloelib/cloelike工具配合使用。数据集生成至最大多极阶数ell=5000,共包含32个ell分箱;采用6个红移分箱,其红移分布n(z)取自Zenodo平台上的另一记录。合成数据与协方差矩阵均通过以下参数生成: 哈勃常数(H0):67.0,冷暗物质当前宇宙学密度分数(Omega_cdm0):0.27,重子物质当前宇宙学密度分数(Omega_b0):0.049,空间曲率当前密度分数(Omega_k0):0.0,中微子总质量(mnu):0.0,暗能量状态方程当前值(w0):-1.0,暗能量状态方程演化项(wa):0.0,原初密度扰动谱指数(ns):0.96,原初密度扰动振幅(As):2.1×10^-9, 'log10TAGN': 7.75, 'AIA': 0.16, 'EtaIA': 1.66, 'b1_photo_poly0': 1.33291, 'b1_photo_poly1': -0.72414, 'b1_photo_poly2': 1.0183, 'b1_photo_poly3': -0.14913, 'magnification_bias_1': 0.0, 'magnification_bias_2': 0.0, 'magnification_bias_3': 0.0, 'magnification_bias_4': 0.0, 'magnification_bias_5': 0.0, 'magnification_bias_6': 0.0, 'dz_pos_1': 0.0, 'dz_pos_2': 0.0, 'dz_pos_3': 0.0, 'dz_pos_4': 0.0, 'dz_pos_5': 0.0, 'dz_pos_6': 0.0, 'multiplicative_bias_1': 0.0, 'multiplicative_bias_2': 0.0, 'multiplicative_bias_3': 0.0, 'multiplicative_bias_4': 0.0, 'multiplicative_bias_5': 0.0, 'multiplicative_bias_6': 0.0, 'dz_shear_1': 0.0, 'dz_shear_2': 0.0, 'dz_shear_3': 0.0, 'dz_shear_4': 0.0, 'dz_shear_5': 0.0, 'dz_shear_6': 0.0
