Member Function Documentation

add_dependence()

void Observable::add_dependence

(

const ParamId &

param_name

)

Add a single parameter dependence.

Parameters

param_name

Parameter id to add to the dependency set.

Definition at line 15 of file Observable.cpp.

add_dependences()

void Observable::add_dependences

(

const std::unordered_set< ParamId > &

param_names

)

Add many parameter dependences.

Performs a set union with the existing dependency set.

Parameters

param_names

Set of parameter ids to add.

Definition at line 19 of file Observable.cpp.

compute()

std::vector< ObservableValue > Observable::compute

(

)

const

Compute the theory prediction for this observable.

This method ensures the underlying DecayParent is enabled before computing. Enabling typically triggers Wilson group building (via ObsWilsonHelper) and parameter loading.

Returns

A vector of observable values (binned or multi-component outputs supported).

Definition at line 11 of file Observable.cpp.

get_dependences()

const std::unordered_set< ParamId > & Observable::get_dependences

(

)

const

Access the dependency set (read-only).

Returns

Reference to internal dependency set.

Definition at line 24 of file Observable.cpp.

get_exp_uncertainty()

scalar_t Observable::get_exp_uncertainty	(	std::pair< double, double >	bins = {0.,0.},
		std::string	exp = "DEFAULT",
		UncertaintyType	u_type = UncertaintyType::COMBINED
	)		const

Get the experimental uncertainty for this observable.

The uncertainty type is mapped to a DataType via UncertaintyTypeMapper::d_type. Typical values include combined/stat/sys depending on your implementation.

Parameters

bins	Experimental bins of the observable
exp	Experiment for the observable
u_type	Which uncertainty component to request (default: combined).

Returns

Experimental uncertainty (as scalar_t).

Definition at line 7 of file Observable.cpp.

get_exp_val()

scalar_t Observable::get_exp_val	(	std::pair< double, double >	bins = {0.,0.},
		std::string	exp = "DEFAULT"
	)		const

Get the experimental central value for this observable.

Reads from the observable parameter proxy using:

• ParamId(ParameterType::OBSERVABLE, "FOBS", ObservableMapper::flha_of(id))

Parameters

bins	Experimental bins of the observable
exp	Experiment for the observable

Returns

Experimental central value (as scalar_t).

Definition at line 3 of file Observable.cpp.

getId()

ObservableId Observable::getId ( ) const

inline

Return the observable id.

Definition at line 87 of file Observable.h.

Member Data Documentation

decay_parent

std::shared_ptr<DecayParent> Observable::decay_parent

protected

Physics backend that computes the theory prediction for this observable.

Definition at line 52 of file Observable.h.

dependences

std::unordered_set<ParamId> Observable::dependences

protected

Set of parameter identifiers the observable depends on.

This is intended for external tooling:

• dependency tracking / invalidation,
• sensitivity studies,
• fit engines (knowing which parameters to vary),
• caching layers.

Definition at line 63 of file Observable.h.

id

const ObservableId Observable::id

protected

Identifier of this observable (used for experimental lookup and theory computation routing).

Definition at line 49 of file Observable.h.

iobspp_obs

std::shared_ptr<IObsParameterProxy<ParamId, DataType, std::string, LhaID> > Observable::iobspp_obs

protected

Proxy to experimental/observable parameters (typically ParameterType::OBSERVABLE).

Expected block usage in current implementation:

• block: "FOBS"
• code : ObservableMapper::flha_of(id)
