Component speeds used to produce marginal and unstable flow profiles.

Profile name Ω1 Ω3 Ω4 Ω2

QK(Ekman) 7.50 1.00 1.00 1.00
QK(q = 1.9) 7.50 2.74 0.77 1.00
QK(Split) 7.50 7.50 1.00 1.00
QK(q = 1.5) 5.91 2.48 1.09 1.00
MS 8.27 3.02 0.83 1.00
CUS 1 9.43 3.43 0.94 1.00
CUS 2 9.43 3.43 0.00 0.00
Solidbody 1.00 1.00 1.00 1.00

Notes. Speeds are listed as a fraction of the Outer Cylinder speed, Ω2. MS is marginally stable, CUS is unstable by the Rayleigh criterion.
