void AliTrackletdNdetaPost::DrawDeltas	(	Container *	realList,

	)

Draw \(\Delta\) distributions for a single bin

Parameters

realList

Definition at line 1063 of file AliTrackletdNdetaPost.C.

Referenced by ProcessBin().

void AliTrackletdNdetaPost::DrawdNdeta	(	Container *	realList,
		Bool_t	realComb,
		Container *	simList,
		Bool_t	simComb,
		Color_t	color = `kBlack`,
		THStack *	stack = `0`,
		TDirectory *	out = `0`,
		Bool_t	alt = `false`
	)

Calculates the result as

\[ R = \frac{P}{(1-\beta\prime)M\prime} (1-\beta)M \]

where

\( P\) is the input primary particle distribution
\( \beta\prime\) is background correction for simulated data
\( M\prime\) is the observed distribution in simulations
\( \beta\) is background correction for real data
\( M\) is the observed distribution in real data

In case we use MC-labels for the background correction in simulations, we have that

\[ (1-\beta\prime)M\prime = (1-C\prime/M\prime)M\prime = M\prime-C\prime \]

where

\( C\prime\) is the observed number of tracklets for which the constituent clusters have different parent simulated traks.

In case we use MC-labels for the background correction for real data, we have that

\[ (1-\beta)M = (1-k\beta\prime)M = (1-kC/M\prime)M \]

where \( k\) is a constant scaling factor (1.3).

If we use injected clusters as an estimator for the background correction in simulations, we have

\[ (1-\beta\prime)M\prime = (1-B\prime/M\prime)M\prime = M\prime-B\prime \]

where

\( B\prime\) is the observed number of tracklets when injecting fake clusters, scaled so that the corresponding \(\Delta\) distribution match the measured (in simulations) \(\Delta\) distribution in the tails ( \(\Delta\in[5,20]\))

The same expression holds for the case when we use injected clusters to estimate the background in real data.

\[ (1-\beta)M = (1-B/M)M = M-B \]

where \( B\) has the same meaning as \( B\prime\) except we use real data.

Note, if we use MC-labels for both the simulated and real data backgrounds, and \( k=1\) we find that

\[ R = \frac{P}{M\prime}M \]

Parameters

realList	List of real data histograms
realComb	Whether to use MC-labels for real data
simList	List of simulated data histograms
simComb	Whether to use MC-labels for simulated data
color	Color to use
stack	Stack to add results to
