Target field orientation (II)
ALT' contribution': µ tan qN (= qq- qB)
qB~10° suppresses ALT' mix to < ½ of qB = 0
Resulting beam deflection qd = 0.33°
Scattered electrons: 35° ± 1.3° (HMS accept.) qd (E'min= 2 GeV) = 5.05°; plane tilt f = 8.5°
Additional ~1/Q suppression of ALT': effective contribution ~ 4 to 7%
