Action-kick sensitivity to D4 field errors at injection (R0 = 25 mm):

Multipole 	|\Delta J/J\right| (10^{-3})
b_2/a_2		0.22
b_3/a_3		0.089
b_4/a_4		0.035
b_5/a_5		0.014
b_6/a_6		0.006
b_7/a_7		0.002
b_8/a_8		0.0009
b_9/a_9		0.0003
b_10/a_10	0.0001
b_11/a_11	0

Note:

1. 1 unit multipole error on one set of D4A+D4B dipole

2. nominal injection; 11 sigma amplitude with zero crossing angle
