config.load_data

config.load_data(data_type, prefix=None)

Loads data from downloaded files.

Parameters:

data_type{‘binning’, ‘dep_tf’, ‘hed_tf’, ‘tf_helper’, ‘ics_tf’, ‘struct’, ‘hist’, ‘f’, ‘pppc’}

Type of data to load. The options are: - ‘binning’ – Default binning for all transfer functions; - ‘dep_tf’ – Transfer functions for propagating photons and deposition into low-energy photons, low-energy electrons, high-energy deposition and upscattered CMB energy rate; - ‘hed_tf’ – Transfer functions for high-energy deposition only; - ‘tf_helper’ – Helper functions used in reconstructing transfer functions (from neural network); - ‘ics_tf’ – Transfer functions for ICS for scattered photons in the Thomson regime, relativistic regime, and scattered electron energy-loss spectrum; - ‘struct’ – Structure formation boosts; - ‘hist’ – Baseline ionization and temperature histories; - ‘f’ – \(f_c(z)\) fractions without backreaction; and - ‘pppc’ – Data from PPPC4DMID for annihilation spectra. Specify the primary channel in primary.

prefixstr, optional

Path to the data directory. If not specified, the path is taken from the environment variable DH_DATA_DIR.

Returns:

dict

A dictionary of the data requested.
