set_print_level_squared_amplitude_rcl(n)

Set the print level for squared amplitudes to n.

Parameters: n (int) – print level n = 0: nothing is printed n = 1: the non vanishining squared amplitudes A2 summed/averaged over colour and helicities are printed at LO and NLO (if NLO is computed) n = 2: in addition to n=1, the NLO (if computed) contributions to A2 from bare-loop, counterterms and rational part are also printed n = 3: prints the squared helicity amplitudes summed/averaged over colour at LO and NLO (if NLO is computed) for each helicity
