Detailed Description

Calculations done per centrality. These objects are only used internally and are never streamed. We do not make dictionaries for this (and derived) classes as they are constructed on the fly.

	)		const

virtual

Calculate the Event-Level normalization.

The full event level normalization for trigger \(X\) is given by

\begin{eqnarray*} N &=& \frac{1}{\epsilon_X} \left(N_A+\frac{N_A}{N_V}(N_{-V}-\beta)\right)\\ &=& \frac{1}{\epsilon_X}N_A \left(1+\frac{1}{N_V}(N_T-N_V-\beta)\right)\\ &=& \frac{1}{\epsilon_X}N_A \left(1+\frac{N_T}{N_V}-1-\frac{\beta}{N_V}\right)\\ &=& \frac{1}{\epsilon_X}N_A \left(\frac{1}{\epsilon_V}-\frac{\beta}{N_V}\right) \end{eqnarray*}

where

\(\epsilon_X=\frac{N_{T,X}}{N_X}\) is the trigger efficiency evaluated in simulation.
\(\epsilon_V=\frac{N_V}{N_T}\) is the vertex efficiency evaluated from the data
\(N_X\) is the Monte-Carlo truth number of events of type \(X\).
\(N_{T,X}\) is the Monte-Carlo truth number of events of type \(X\) which was also triggered as such.
\(N_T\) is the number of data events that where triggered as type \(X\) and had a collision trigger (CINT1B)
\(N_V\) is the number of data events that where triggered as type \(X\), had a collision trigger (CINT1B), and had a vertex.
\(N_{-V}\) is the number of data events that where triggered as type \(X\), had a collision trigger (CINT1B), but no vertex.
\(N_A\) is the number of data events that where triggered as type \(X\), had a collision trigger (CINT1B), and had a vertex in the selected range.
\(\beta=N_a+N_c-N_e\) is the number of control triggers that were also triggered as type \(X\).
\(N_a\) Number of beam-empty events also triggered as type \(X\) events (CINT1-A or CINT1-AC).
\(N_c\) Number of empty-beam events also triggered as type \(X\) events (CINT1-C).
\(N_e\) Number of empty-empty events also triggered as type \(X\) events (CINT1-E).

Note, that if \( \beta \ll N_A\) the last term can be ignored, and the expression simplyfies to

\[ N = \frac{1}{\epsilon_X}\frac{1}{\epsilon_V}N_A \]

Parameters

t	Histogram of triggers
scheme	Normalisation scheme
trgEff	Trigger efficiency
ntotal	On return, the total number of events to normalise to.
text	If non-null, fill with normalization calculation

Returns: \(N_A/N\) or negative number in case of errors.
