Slits

Slits are introduced by the following assignments. They are part of /online_dir/exp_ini.exp

SLT1_BOTTOM   = E2_MOT17
SLT1_TOP      = E2_MOT18
SLT1_RIGHT    = E2_MOT19
SLT1_LEFT     = E2_MOT20
SLT2_BOTTOM   = E2_MOT21
SLT2_TOP      = E2_MOT22
SLT2_RIGHT    = E2_MOT23
SLT2_LEFT     = E2_MOT24
