Output data file format





For each kinematics(e.g., for each input file), each of these Fortran and C codes will write the results of cross section into two data files. For example, epc.f will generate two data files 'epc.dat' and 'epc_tot.dat'. 'Epc.dat' is a list of electron final momentum(in MeV/c) and the corresponding cross section in unit of (nb/GeV-sr), where the step in electron final momentum is given in the input file. It could be used for estimating how cross section changes within the current momentum setting (here we interpret $p_{min}$ and $p_{max}$ as the momentum acceptance of electron spectrometer). The other output file 'epc_tot.dat' gives the number of points, sum of cross sections of each step and the average cross section for the current momentum setting. This is the source file for writesum.c.
Examples of output file 'epc.dat' and 'epc_tot.dat' are also in the rate.tar.gz:
epc.dat:
$\displaystyle x$ $\textstyle p_e$ $\displaystyle \sigma (nb/GeV-sr)$  
$\displaystyle 0.181811579$ $\textstyle 528.$ $\displaystyle 0.643409365$  
$\displaystyle 0.185617372$ $\textstyle 538.$ $\displaystyle 0.630819511$  
$\displaystyle 0.189438085$ $\textstyle 548.$ $\displaystyle 0.618768662$  
$\displaystyle 0.193273804$ $\textstyle 558.$ $\displaystyle 0.607224655$  
$\displaystyle 0.197124618$ $\textstyle 568.$ $\displaystyle 0.596157697$  

epc_tot.dat:
$\displaystyle 5$ $\textstyle 3.09637989$ $\displaystyle 0.619275978$
