Action-kick sensitivity to D1 field errors at collision (R0 = 25 mm):

Multipole 	|\Delta J/J\right| (10^{-3})
b_2/a_2		4.08
b_3/a_3		2.48
b_4/a_4		1.51
b_5/a_5		0.93
b_6/a_6		0.57
b_7/a_7		0.35
b_8/a_8		0.21
b_9/a_9		0.13
b_10/a_10	0.08
b_11/a_11	0.05
Note:

1. 1 unit multipole error on one D1 dipole

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