# Example multiplicity calibration macros
2+
3+
You will find some example macros in this directory that will allow for the calculation of a glauber fit and the corresponding calibration histograms.
4+
5+
A simplified description of the procedure necessary to generate a
6+
Glauber + NBD fit to a certain histogram is described below.
7+
8+
## Performing a Glauber + NBD fit
9+
10+
### First step: calculation of Glauber MC sample
11+
12+
The Glauber + NBD model assumes that the multiplicity / amplitude
13+
distribution that one intends to fit can be described as coming
14+
from a certain number N_{ancestor} of particle-emitting sources called 'ancestors'. Each ancestor is assumed to produce particles
15+
according to a negative binominal distribution. Further,
16+
the number of ancestors is assumed to be related to the basic
17+
glauber quantities N_{part} and N_{coll} via the formula:
18+
19+
N_{ancestor} = f * N_{part} + (1-f) N_{coll}
20+
21+
Usually, the value f is fixed at 0.8, and thus the range of
22+
N_{ancestors} is typically 0-700 in Pb-Pb collisions.
23+
24+
In order to allow for Glauber + NBD fitting, the correlation of
25+
(N_{part}, N_{coll}) needs to be known. For that purpose,
26+
a tree of Glauber MC needs to be generated using TGlauberMC using the relevant nuclei, which also involves choosing an appropriate nuclear profile.
27+
28+
Once TGlauberMC has been used to produce a tree with N_{part} and
29+
N_{coll} values, their correlation needs to be saved to a 2D histogram that serves as input to the Glauber + NBD fitter used in
30+
O2/O2Physics. This is done using the macro called `saveCorrelation.C` contained in this directory, which produces a file named `baseHistos.root`. The file `saveCorrelation.C` serves as
31+
an example for the Pb-Pb case and minor adaptation may be needed
32+
in case other nuclei are to be used.
33+
34+
### Second step: execution of Glauber + NBD fitter
35+
36+
The fitting procedure is done via the macro ``. Because
37+
the numerical fitting utilizes a convolution of a N_{ancestor}
38+
distribution and NBD distributions, it will not be as fast
39+
as typical one-dimensional fits: typical times of 10-100 seconds
40+
are not unusual. The macro will produce an output file
41+
that contains:
42+
43+
* the original fitted histogram
44+
* the actual glauber fit distribution, plotted all the way
45+
to zero multiplicity
46+
47+
This output can then be used to extract percentiles.
48+
49+
### Third step: calculation of percentile boundaries
50+
51+
Once both the data and glauber fit distributions are known,
52+
the next step is to create a 'stitched' data/glauber distribution in
53+
which the distribution at low multiplicities follows
54+
the glauber fit and the distribution at higher multiplicities
55+
follows the data. The multiplicity value in which the switch from
56+
glauber to data takes place is called 'anchor point'.

Because of the fact that this 'stitching' procedure may need to be tuned and the actual glauber fit is slow, the stitching is done
59+
in a separate macro called `runCalibration.C`. It is provided
60+
in this directory as well and it is the third and last step in calculating percentile boundaries. The macro will printout some
61+
key boundaries as well as save an output file with the calibration.

*Bonus*: at the stage in which the glauber fit has been done
64+
and all information is available, a de-convolution process
65+
can be used to calculate the average N_{part} and N_{coll}
66+
in centrality slices. This functionality is also provided
67+
in O2Physics as part of the `multGlauberNBDFitter` and the
68+
`runCalibration.C` macro can optionally also perform that
69+
deconvolution. *Warning*: this procedure might take a mooment.
