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

Multipole 	|\Delta J/J\right| (10^{-3})
b_2/a_2		0.20
b_3/a_3		0.10
b_4/a_4		0.054
b_5/a_5		0.028
b_6/a_6		0.015
b_7/a_7		0.008
b_8/a_8		0.004
b_9/a_9		0.002
b_10/a_10	0.001
b_11/a_11	0.0006

Note:

1. 1 unit multipole error on one D1 dipole

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