Figure 1 shows response to correctors at the left and response to SHMS magnets starting around 1150. Top panel shows XPOS and one of the horizontal lock correctors. 3H09.XPOS responds only to the H corrector which 3H08 responds to both X (top panel) and Y corrector (middle panel) as blue trace has two bumps.
In the middle panel one sees that 3H08.YPOS has two bumps, one each for H and V correctors, while 3H09.YPOS reacts only to V corrector.
The bottom panel shows the SHMS magnets. One sees expected large response in XPOS to HB and Q2 magnets and little or no response in YPOS.
