Excitation, offset range 20kHz, no RF-inhomogeneity.
All pulses are optimized with 0.5us digitization and the number in the pulse
name corresponds to the number of points in the shape, so e.g. pulse5 is 2.5us long pulse.
Names like pulse5 represent pulse shapes in the following format:
[x-component, y-component, duration(us)], while names like pulse5.bruker represent shapes
in the following format: [amplitude(%), phase].
