Blinding

These stages deal with blinding measurements

• TXBlinding - Blinds real-space measurements following Muir et al

• TXNullBlinding - Pretend to blind but actually do nothing.

class txpipe.blinding.TXBlinding(args, comm=None, aliases=None)

Blinds real-space measurements following Muir et al

This stage computes the shift in theory predictions between a fiducial cosmology and a cosmology randomly chosen based on a seed value.

It then applies that shift to the observations in a sacc file.

Inputs:

• twopoint_data_real_raw: SACCFile

Outputs:

• twopoint_data_real: SACCFile

Parallel: No - Serial

Configuration

• seed: (int) Default=1972.
• Omega_b: (list) Default=[0.0485, 0.001].
• Omega_c: (list) Default=[0.2545, 0.01].
• w0: (list) Default=[-1.0, 0.1].
• h: (list) Default=[0.682, 0.02].
• sigma8: (list) Default=[0.801, 0.01].
• n_s: (list) Default=[0.971, 0.03].
• b0: (float) Default=0.95.
• delete_unblinded: (bool) Default=False.

class txpipe.blinding.TXNullBlinding(args, comm=None, aliases=None)

Pretend to blind but actually do nothing.

This null stage trivially copies the real raw data to real without blinding, for use with simulated data, etc.

Inputs:

• twopoint_data_real_raw: SACCFile

Outputs:

• twopoint_data_real: SACCFile

Parallel: No - Serial
