The scanning tunnelling spectroscopy results from (Ca2-xNax)CuO2Cl2 in a strong magnetic field are reinterpreted in a substantially different fashion. Instead of looking, as Hanaguri et al do, to a B1g BCS-based interpretation and relying heavily upon 'coherence effects', the very detailed changes wrought in the tunnelling characteristics are re-addressed following the present author's negative-U, boson-fermion, resonant crossover modelling of the High Temperature Superconducting Cuprate (HTSC) phenomenon. As with a great many other now quite sophisticated and discriminatory experimental assaults on the latter problem, it would once again appear this form of modelling has much to offer a full solution to this long-standing matter.
