Optimization of the SLIC-pulse amplitude, ${\mathit{\nu }}_1$, for generating the LLS in trans-AB. Duration of the SLIC-pulse was ${\mathit{\tau }}_{\mathit{rf}}=0.3$ s, the delay between the two SLIC pulses was $\mathit{\tau }=10$ s. Here the time $\mathit{\tau }$ was fixed, and we assume the same relaxation contribution to each of the measured points, $B_0=16.4$ T. The signal intensity is given in percent of the thermal signal of trans-AB
