Trying to get the equilibrium emittance values for a lattice with not perfectly closed orbit on the transverse plane, but stable on the longitudinal plane. EMIT command only gives the first part of the output. RF is on and RADIATE=true.

Is the stability on the transverse plane also a strict requirement?
