Set the print level for amplitudes to n.

Parameters:n (int) –

print level

  • n = 0: nothing is printed
  • n = 1: the non vanishining amplitudes A(c,h) are printed at LO
    and NLO (if NLO is computed) for each coulour structure and helicity state
  • n = 2: reports individual NLO (if computed) contributions, i.e.
    bare-loop, counterterms and rational parts are printed separately
