Synthetic data (2PCF multipoles and polar) for GCspectro post-reconstruction

Description: Includes multipoles of the 2PCF and 2PCF polar post-reconstruction from smin=0 Mpc/h to smax=200 Mpc/h with a linear binning of 1 Mpc/h, to be used with the blinding notebook. 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). The synthetic data were generated with the publicly available code BeXiCov, using  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]),}
