Appendix A: another analytical solution with degenerate light cylinder

Here we give the analytical expression for the field pressure and flux distribution for a solution with and a bounded current distribution (22) with ,

The field rotation law can be expressed by an implicit equation

Suppose that we have Keplerian rotation of the foot points along the disk, , it follows for the disk flux distribution

where . For the 'total expansion rate' of the jet we derive an implicit equation
