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

Multipole 	|\Delta J/J\right| (10^{-3})
b_2/a_2		0.23
b_3/a_3		0.13
b_4/a_4		0.073
b_5/a_5		0.041
b_6/a_6		0.023
b_7/a_7		0.013
b_8/a_8		0.008
b_9/a_9		0.004
b_10/a_10	0.002
b_11/a_11	0.001

Note:

1. 1 unit multipole error on one D2 dipole

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