pybird.io_pb module

pybird.io_pb.get_dict_from_hdf5(group, none_flag=nan)

Recursively read data from an HDF5 group into a Python dictionary.

Parameters:

• group (h5py.Group) – HDF5 group to read from.

• none_flag (float, optional) – Value used to represent None in the HDF5 file. Defaults to float(“nan”).

Returns:

Dictionary containing all datasets and subgroups from the HDF5 group.

Return type:

dict

pybird.io_pb.save_dict_to_hdf5(group, data, none_flag=nan)

Recursively save a Python dictionary to an HDF5 group.

Parameters:

• group (h5py.Group) – HDF5 group to write to.

• data (dict) – Dictionary to save to HDF5.

• none_flag (float, optional) – Value to use when saving None values. Defaults to float(“nan”).

class pybird.io_pb.ReadWrite

Bases: object

A class for reading, writing, and formatting cosmological data files.

This class handles I/O operations for cosmological power spectra and correlation functions, including reading HDF5 files, formatting data for analysis, and writing results to various output formats.

Type:

all data is passed through method parameters

read()

Read data from HDF5 file and format for analysis.

check()

Validate data against configuration parameters.

config()

Prepare configuration dictionary for correlator.

format()

Format raw data for analysis.

write()

Write results to output files.

write_common()

Write common cosmological parameters to output.

write_pk()

Write power spectrum data to output.

write_cf()

Write correlation function data to output.

write_bao_rec()

Write BAO reconstruction data to output.

set_header()

Create header for output files.

get_wedge_rotation_matrix()

Get matrix for multipole to wedge conversion.
