Mike,

The transverse kick is why we never use MQJ0L01: add the feeddown to the 
transverse momentum and the correctors are too feeble.  Steer to center 
the beam before 0L02 and one can get by.  The peak beam envelope is 
large (~2.5 mm sigma) as one develops the FODO lattice through 
0L02/0L02A, 0L03A/0L03, 0L04.  That's why I wanted to switch to solenoid 
focusing in the 6 MeV region.
