Function/Subroutine Documentation

subroutine, public eftcamb_stability::eftcamb_stability_check	(	logical, intent(out)	success,
		class(eftcamb), intent(in)	input_EFTCAMB,
		type(eftcamb_parameter_cache), intent(inout)	params_cache,
		real(dl), intent(in)	astart,
		real(dl), intent(in)	aend,
		real(dl), intent(inout)	k_max
	)

Subroutine that tests the stability of a theory in a time range. To ensure best time coverage scans with three different strategies.

Parameters

[out]	success	Output of the subroutine. Tells whether the model is found stable or not.
[in]	input_eftcamb	the EFTCAMB object for which the code is computing stability.
[in,out]	params_cache	the EFTCAMB parameter cache that contains all the physical parameters.
[in]	astart	Initial scale factor.
[in]	aend	Final scale factor.
[in,out]	k_max	the input maximum k mode at which stability is computed.

subroutine, public eftcamb_stability::eftstability_cleanup

(

)

Subroutine that restores the values stored in the module to the default. Needed for successive calls.

subroutine, public eftcamb_stability::eftstabilitycomputation	(	real(dl), intent(in)	a,
		class(eftcamb_model), intent(in)	input_model,
		type(eftcamb_parameter_cache), intent(inout)	params_cache,
		type(eftcamb_timestep_cache ), intent(inout)	eft_cache
	)

Subroutine that fills the caches to check the stability of the theory.

Parameters

[in]	a	the input scale factor.
[in]	input_model	the EFTCAMB model for which the code is computing the RGR time.
[in,out]	params_cache	the EFTCAMB parameter cache that contains all the physical parameters.
[in,out]	eft_cache	the EFTCAMB timestep cache that contains all the physical values.

logical function, public eftcamb_stability::eftteststability	(	real(dl), intent(in)	a,
		real(dl), intent(inout)	k_max,
		class(eftcamb), intent(in)	input_EFTCAMB,
		type(eftcamb_parameter_cache), intent(inout)	params_cache
	)

Function that fills the caches to check the stability of the theory.

Parameters

[in]	a	the input scale factor.
[in,out]	k_max	the input maximum k mode at which stability is computed.
[in]	input_eftcamb	the EFTCAMB object for which the code is computing stability.
[in,out]	params_cache	the EFTCAMB parameter cache that contains all the physical parameters.

Returns

Logical value returned by the function. If the model is stable this is True, otherwise False.
