Figure 4. Fits to the ratio R 0 ; p (de(cid:12)ned in eq. (3.7)) at a momentum transfer q = (cid:0) p = (cid:0) ; O 2 (cid:25) (0 ; 0 ; (cid:0) 1) T for ensemble D200 (left side) and C101 (right side) for various channels and spin L projections, where we have exploited rotational symmetry to average over equivalent directions. The solid lines correspond to a simultaneous (cid:12)t to all the channels taking into account the leading N(cid:25) contribution using eqs. (2.44) and (2.45). The yellow band corresponds to the ground state. The gray band (dashed lines) shows the ground state extracted from a traditional (cid:12)t using one generic excited state. The ground state contributions in the top (bottom) panels are sensitive to G A ( G P ), exclusively, while those in the second and the third row yield linear combinations of G A and G ~ (see eqs. (A.3){(A.6)). The bands include the statistical error and an error due to a P variation of the (cid:12)t
