Top plot: IFU coupling functions for the 7 fibers, when centering an object on each of them ( $ρ_{i}^{s} (r_{o f f})$ $\[\rho_i^s(\boldsymbol{r}_{\mathrm{off}})\]$ of Section 4.2). Bottom plot: IFU coupling functions for the 6 off-axis fibers, when centering an object in the central spaxel-fiber 0 ( $ρ_{i}^{s} (r_{on})$ $\[\rho_{i}^{s}(\boldsymbol{r}_{\text {on}})\]$ of Section 4.2). We considered median conditions of seeing (0.76″) and elevation (43°).
