Bool_t AliTrackletdNdeta2::Deltas0D	(	Container *	realCont,
		Container *	simCont,
		TDirectory *	outParent
	)

Get $ \Delta$ distributions but only scale those from injection. In this member function, we use a fixed scaling factor of 1 except for the injection distribtions, where we use the integrated scaling factors. That is, we extract the scaling factors as

\[ k_{XY} = \frac{\int_{\mathrm{tail}}d\Delta_{X}\frac{dN}{d\Delta_{X}}}{ \int_{\mathrm{tail}}d\Delta_{Y}\frac{dN}{d\Delta_{Y}}} \]

where $ X,Y$ are either $ M, I$ or $ M', I'$

Parameters

realCont	Container of real distributions
simCont	Container of simulated distributions
outParent	Parent directory for output

Returns: true on success

Get $ \Delta$ distributions and scale them appropriately. In this member function, we use the integrated scaling factors (e.g., as done in the past). That is, we extract the scaling factors as

\[ k_{XY} = \frac{\int_{\mathrm{tail}}d\Delta_{X}\frac{dN}{d\Delta_{X}}}{ \int_{\mathrm{tail}}d\Delta_{Y}\frac{dN}{d\Delta_{Y}}} \]

where $ X,Y$ are one of $ M, M', I, I'$
