This submodule defines a cylindrical equilibrium in which a Suydam surface
is present, such that this gives rises to Suydam cluster modes.
The geometry can be overriden using the parfile.
This equilibrium is taken from

Note
Default values are given by
- k2 = 1
- k3 = -1.2
- cte_rho0 = 1 : used to set the density value.
- cte_p0 = 0.05 : used to set the background pressure.
- cte_v02 = 0 : sets a constant flow .
- cte_v03 = 0.14 : prefactor for flow profile .
- p1 = 0.1 : constant that appears in magnetic field and pressure components.
- alpha = 2 : used in the Bessel functions.
and can all be changed in the parfile.
