Figure 6. Comparison to the subtraction method proposed in ref. [60] for the ratio R 0 ; p (de(cid:12)ned (cid:0) ; O in eq. (3.7)) at the momentum transfer q = (cid:0) p = 2 (cid:25) (0 ; 0 ; (cid:0) 1) T for ensemble D200. The solid and L dashed lines show (cid:12)ts to the unsubtracted and subtracted data, respectively, where the yellow and red bands show the corresponding ground state signals. In both cases we have taken into account the leading N(cid:25) contribution. For the subtracted current the (cid:12)t ansatz has to be adapted, cf. appendix B.
