Detailed Description

Generic libraries, parameters and functions used in the whole code.

Data Structure Documentation

◆ precision

struct precision

All precision parameters.

Includes integrations steps, flags telling how the computation is to be performed, etc.

Data Fields
double	smallest_allowed_variation	machine-dependent, assigned automatically by the code
ErrorMsg	error_message	zone for writing error messages

Enumeration Type Documentation

◆ evolver_type

enum evolver_type

parameters related to the precision of the code and to the method of calculation list of evolver types for integrating perturbations over time

◆ pk_def

enum pk_def

List of ways in which matter power spectrum P(k) can be defined. The standard definition is the first one (delta_m_squared) but alternative definitions can be useful in some projects.

Enumerator
delta_m_squared	normal definition (delta_m includes all non-relativistic species at late times)
delta_tot_squared	delta_tot includes all species contributions to (delta rho), and only non-relativistic contributions to rho
delta_bc_squared	delta_bc includes contribution of baryons and cdm only to (delta rho) and to rho
delta_tot_from_poisson_squared	use delta_tot inferred from gravitational potential through Poisson equation

◆ file_format

enum file_format
