This directory contains various codes for simulating runs of events with 
anisotropic flow (v1,v2,v4) and mock-up nonflow effects (emission of 
particles by pairs or quadruplets), and for analysing them (with cumulants, 
with Lee-Yang zeroes). 

 - Bessel.c, Bessel.h: library with the Bessel functions J_0, J_m.

 - cumulants.cc: implementation of the "cumulant" method, using the 
generating function advocated in Phys. Rev. C 64 (2001) 054901.
Should be compiled together with distributions.cc.
NOTE (May.5, 2008): there are mistakes in the computation of statistical 
error bars (the resolution parameter is ill-computed, the error bar on 
integrated V{6} should be checked, that on differential v{5} implemented); 
to be solved (hopefully) soon! 

 - distributions.cc, distributions.h: contain several functions (momentum 
distribution, flow pT-profiles) for the generation of events.

 - generator.cc: event generator. 
Should be compiled with distributions.cc and hasard.c.
NOTE (June 20, 2006): a feature I have not imported from previous versions 
of this program is the possibility to let the flow magnitude fluctuate from 
event to event. I plan to add it...

 - hasard.c, hasard.h: random number generator.

 - inputdata.dat: contains inputs (number of events, number of particles 
per event) for the generation of events.

 - zeros.cc: implementation of the "Lee-Yang zeroes" method, using the 
generating function of J. Phys. G 30 (2004) S1213.
Should be compiled with Bessel.c and distributions.cc. 

 - zeros_v1.cc: implementation of the Lee-Yang zeroes method for the 
analysis of v1, following Nucl. Phys. A 742 (2004) 130. 
Should be compiled with Bessel.c and distributions.cc. 

---

To be added later (May 5, 2008): 

 - cumulants_v1.cc: implementation of the three-particle cumulant method 
(analysis of v1), as in Phys. Rev. C 66 (2002) 014905. 

... and even later: 

 - cumulants-bis.cc: implementation of the cumulant method in the version 
with flow vectors, as originally developed in Phys. Rev. C 63 (2001) 
054906. 
Note that the version implemented in cumulants.cc is our (the authors') 
recommended one. 

- zeros-bis.cc: implementation of the Lee-Yang zeroes method in the version 
with flow vectors, as originally developed in Nucl. Phys. A 727 (2003) 373.
Note that the version implemented in zeros.cc is the recommended one.
