Current issue: where is the fxt holder?

• Previous vertice checks did not seem to show any scattering off of it
• Below plots show vertices of secondary tracks in the 1.6 m – 2.4 m region
• Only the beam pipe (inner radius of ~3.9 cm)

Is it in the geometry files?

• Geometry described in: $STAR/StarVMC/Geometry/
• StarGeo.xml says y2018 has pipe ("PIPE12ft") and target ("TARGv1"), y2018a not.
• PIPE12ft has pipe, sets targflag=1, PipeGeo: "1=add fixed target"
• targflag=1 seems to trigger some konly="MANY" settings
• Not fully clear at this moment what is going on
• Asked Jason for clarification
• Should also probably rerun the secondary vertex check, just to be on the safe side…
