V = 1.2 // X-component velocity lower range
// Caluclations
// The fraction of molecules with positive x-component of velocity = 0.5
F_mol = 0.5
// F = (1/sqrt(%pi))integrate(exp(-X^2),'X',0,1.2)
F_0 = 0.5*erf(V)
// The fraction of molecules with positive X-Component of velocity greater then 1.2Vmp
F_12 = F_mol - F_0
// Output results
