The results of the fits don't look good without Lagrange multipliers, and with them they don't quite have the right rotations for the disks. For example, at 3.8T Celso finds for YE+1 PhiX=.000035, PhiY=-.000297. The fits give -.00016 and .00027 respectively. Comparison for YE+3 is problematic, since the survey was pre-field, and we expect the disk to fit itself to inner ones when the field is on.
