EXERCISEUsing micrOMEGAs tools write your own program for calculation Ωh 21) Caution : vSigma returns value in pb. 1pb=1/3.8937966E8GeV^22) To solve differential equation write a function which calculates derivativevoid derive( double logS, double *Y, double * dYdlogS){ .... * dYdlogS=... }And use odeint(&Y, 1 , logS_start, logS_fin, Eps, H, derive);to solve equation by Runge-Kutta methodEps – precisionH – initial stepY =Yeq at start and contains observed Y after integration.3) Caution: Step of integration will be about 1/γ(T) . Do not start from veryhigh temperature!4) write in <strong>the</strong> top of your file#include"../sources/micromegas.h"#include"../sources/micromegas_aux.h"37
