Analysis of anisotropic flow

Below are a few programs implementing various methods for analyzing anisotropic flow in high-energy nucleus-nucleus collisions.
I also provide a longer description of each program as well as a file listing the minor bugs I might have found in the codes.

• generator.cc:  toy event generator, creating events made of particles with a realistic distribution in transverse momentum p_T, with flow profiles v₁(p_T), v₂(p_T), and v₄(p_T).
  The program relies on the random-number generator hasard.c (header file: hasard.h) and on a few functions defined in distributions.cc (header file: distribution.h), and reads some input from the file inputdata.dat.


• cumulants.cc:  implementation of the "cumulant" method introduced in Phys. Rev. C 64 (2001) 054901.


• zeros.cc:  implementation of the "Lee-Yang zeroes" method described in J. Phys. G 30 (2004) S1213.


• zeros_v1.cc:  implementation of the "Lee-Yang zeroes" method for analyzing v₁ introduced in Nucl. Phys. A 742 (2004) 130.


• Bessel.c (header file: Bessel.h) provides the Bessel functions J₀(x) and J_m(x) for real-valued x.
