Action-kick sensitivity to D2 field errors at collision (R0 = 25 mm):

Multipole 	|\Delta J/J\right| (10^{-3})
b_2/a_2		1.71
b_3/a_3		0.67
b_4/a_4		0.26
b_5/a_5		0.10
b_6/a_6		0.040
b_7/a_7		0.016
b_8/a_8		0.0062
b_9/a_9		0.0024
b_10/a_10	0.0010
b_11/a_11	0.0004
Note:

1. 1 unit multipole error on one D2 dipole

2. beta*=0.5 m; 11 sigma amplitude with zero crossing angle
