Syntax

    contact_curve=beamdnp(spin_system,parameters,H,R,K)

Arguments

    H - Hamiltonian matrix, received from context function

    R - relaxation superoperator, received from context function

    K - kinetics superoperator, received from context function

    parameters.irr_powers - microwave amplitude (aka electron
                            nutation frequency), Hz 

    parameters.rho0       - initial state

    parameters.coil       - detection state

    parameters.pulse_dur  - two pulse durations, seconds
