BiGlobal results showing traces of different varicose modes with frequency of 135 kHz, (a) phase velocities, (b) growth rates and (c) S factor. The star, , depicts the neutral location where the mode becomes unstable. The solid line represents the PSE3D results initiated by mode V1. Mode synchronization regions are indicated by dashed circles. The black line denotes the continuous spectrum and the grey region depicts the nearby stable modes
