Horizontal and vertical slit sets to define the beam profile
For routinely aligning the slits use the offsets (ho and vo).
# (Slit Number)
s# 'enter' - displays the current slit positions
Motors:
s#.u (up)
s#.d (down)
s#.l (left) or s#.n (north)
s#.r (right) or s#.s (south)
s#(hg, vg) - to modify values
-user value at zero when clipping the beam in half
-fully open ~ 20x20
XPP 5 slits:
S0 in the FEE, before HOMS
S1 in SB1, after HOMS (Si3N2 low Z)
S2 in SB2, after Monos (Si3N2 low Z)
S3 in SB2, right after S2 (Ta for high Z)
S4 in SB3, after HRM (Ta for high Z)
Pseudomotors:
s#.ho (horizontal offset)
s#.vo (vertical offset)
s#.hg (horizontal gap)
s#.vg (vertical gap)
