Syntax (call from powder context)::

         dnp=noveldnp_steady(spin_system,parameters,H,R,K)

Syntax

dnp=noveldnp_steady(spin_system,parameters,H,R,K)

Arguments

H - Hamiltonian matrix, received from
        context function

    R - relaxation superoperator, received
        from context function, must be ther-
        malised to some finite temperature

    K - kinetics superoperator, received
        from context function

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

    parameters.coil         - detection state(s)

    parameters.contact_dur  - contact time, seconds

    parameters.shot_spacing - delay between microwave irradiation periods

    parameters.flippulse    - 0: Solid Effect (no flip pulse)
                              1: NOVEL (90-degree flip pulse)

    parameters.flipback     - 0: NOVEL without flipback pulse
                              1: NOVEL with flipback pulse

    parameters.addshift     - shift to center the field profile

    parameters.el_offs      - microwave resonance offsets

Outputs

dnp                     - steady state observable on the de-
                              tection state vector as a function
                              of microwave resonance offset
