UShort_t AliFMDQAChecker::CheckESD	(	AliRecoParam::EventSpecie_t	specie,
		TH1 *	hist
	)		const

protected

Check ESD. Does a simple test of whether the histogram is empty or not.

Parameters

specie	Event specie
hist	Histogram to check

Returns: 0 if all is good, increasing severity for increasingly bad data

UShort_t AliFMDQAChecker::CheckFit	(	TH1 *	hist,
		const TFitResultPtr &	res,
		Double_t	low,
		Double_t	high,
		Int_t &	color
	)		const

protected

Add fit results to to plot

Parameters

hist	Histogram
res	Fit result
color	Color to use for the text - depends on quality
low	Lower bound on fit range
high	Upper bound on fit range

UShort_t AliFMDQAChecker::CheckOne	(	AliQAv1::ALITASK_t	what,
		AliRecoParam::EventSpecie_t	specie,
		TH1 *	hist
	)		const

protected

Check one histogram

Parameters

specie	Event specie
hist	Histogram to check

Returns: 0 if all is good, increasing severity for increasingly bad data

UShort_t AliFMDQAChecker::CheckRaw	(	AliRecoParam::EventSpecie_t	specie,
		TH1 *	hist
	)		const

protected

Check raw input. If the reconstructor is enabled, then we try to fit

\[ f(\Delta;\Delta_p,\xi,\sigma) = \int_{-\infty}^{\infty}d\Delta_p' f_{L}(\Delta;\Delta_p',\xi) \times e^{\frac{(\Delta-\Delta_p')^2}{\sigma^2}} \]

where \(f_L\) is the Landau distribution, to the data. The quality is set according to the value of \(\chi^2/\nu\).

If no reconstructor is set, then simply check that the histogram isn't empty

Parameters

specie	Event specie
hist	Histogram to check

Returns: 0 if all is good, increasing severity for increasingly bad data

Referenced by CheckOne().

UShort_t AliFMDQAChecker::CheckRec	(	AliRecoParam::EventSpecie_t	specie,
		TH1 *	hist
	)		const

protected

Check reconstruction points. Does a simple test of whether the histogram is empty or not.

Parameters

specie	Event specie
hist	Histogram to check

Returns: 0 if all is good, increasing severity for increasingly bad data

UShort_t AliFMDQAChecker::CheckSim	(	AliRecoParam::EventSpecie_t	specie,
		TH1 *	hist
	)		const

protected

Check simulation output. Does a simple test of whether the histogram is empty or not.

Parameters

specie	Event specie
hist	Histogram to check

Returns: 0 if all is good, increasing severity for increasingly bad data

task	What to show
mode	Mode
