TH1 * AliTrackletAODUtils::AverageOverIPz	(	TH2 *	h,
		const char *	name,
		UShort_t	mode,
		TH1 *	ipz,
		Double_t	ipEff = `0`,
		TH2 *	mask = `0`,
		Bool_t	verb = `false`
	)

static

Average primary particle \(\mathrm{d}N_{\mathrm{ch}}/\mathrm{d}\\eta\) over \(\mathrm{IP}_z\)

Mode can be one of

0: Scale average by content of ipz and do error propagation
1: Only propagate errors from ipz (no scale)
2: Do not propagate errors or scale by ipz

If mode is less than 2, and ipEff is non-zero, then we scale the histogram ipz by the inverse vertex efficiency.

Parameters

h	Histogram
name	Name of projection
mode	Mode of operation.
ipz	Vertex distribution
ipEff	IP efficiency \( \varepsilon_{V}\)
mask	Optional mask - if a bin is zero here, do not count it in average.
verb	Whether to be verbose

Returns: Newly allocated histogram or null

static TH2* AliTrackletAODUtils::ProjectEtaDelta ( TH3 * h )

static

Project (integrate)

\[ \frac{\mathrm{d}^3N}{\mathrm{d}\eta\mathrm{d}\Delta\mathrm{dIP}_z} \]

over \(\mathrm{IP}_z\) to return

\[ \frac{\mathrm{d}^2N}{\mathrm{d}\eta\mathrm{d}\Delta} \]

The integral is scaled to number of bins, that is, we calculate the weighted average over \(\mathrm{IP}_z\)

\begin{eqnarray*} N(\eta,\Delta) &=& \sum_{\mathrm{IP}_z} w N(\eta,\Delta,\mathrm{IP}_z)\\ \delta N(\eta,\Delta) &=& \sqrt{1/\sum_{\mathrm{IP}_z} w}\\ w &=& \delta N(\eta,\Delta,\mathrm{IP}_z) \end{eqnarray*}

Parameters

h	3D histogram to integrate

Returns: Newly allocated projection
