State

class zdm.parameters.State[source]

Bases: myData

Central configuration object containing all model parameters.

The State class aggregates all parameter dataclasses into a single object that is passed to Grid, Survey, and other components. It provides dictionary-like access to parameter groups and methods for updating parameters.

analysis

Analysis-level settings.

Type:: AnalysisParams

cosmo

Cosmological parameters.

Type:: CosmoParams

FRBdemo

FRB population parameters.

Type:: FRBDemoParams

rep

Repeater parameters.

Type:: RepeatParams

MW

Milky Way parameters.

Type:: MWParams

host

Host galaxy parameters.

Type:: HostParams

IGM

IGM parameters.

Type:: IGMParams

width

Width distribution parameters.

Type:: WidthParams

scat

Scattering parameters.

Type:: ScatParams

energy

Energy function parameters.

Example

>>> state = State()
>>> state.cosmo.H0
67.66
>>> state['cosmo'].H0  # Dictionary-style access
67.66
>>> state.update_param('gamma', -1.5)

Methods Summary

`set_astropy_cosmo`(cosmo)	Import cosmological parameters from an astropy Cosmology object.
`set_dataclasses`()	Initialize all parameter dataclass instances with defaults.
`update_param`(param, value)	Update a single parameter by name.

Methods Documentation

set_astropy_cosmo(cosmo)[source]

Import cosmological parameters from an astropy Cosmology object.

Parameters:: cosmo (astropy.cosmology.Cosmology) – Astropy cosmology object (e.g., Planck18, WMAP9).

set_dataclasses()[source]: Initialize all parameter dataclass instances with defaults.

update_param(param: str, value)[source]

Update a single parameter by name.

Automatically finds which dataclass contains the parameter and updates it. Handles special cases like H0 updating Omega_b.

Parameters:

param (str) – Parameter name (e.g., ‘H0’, ‘gamma’, ‘lEmax’).
value (any) – New value for the parameter.

__init__()[source]

set_dataclasses()[source]: Initialize all parameter dataclass instances with defaults.
