As per Aidan's request, I have added the missing razor blade beam dump to a specific mirror on the HWSX path on the table.  See attached - although it's a picture of LLO's HWS table, ours now has a beam dump in the circled location.  Although Aidan may elaborate more, basically he asked for this since he sees evidence of scatter coming from this path.

Note, there is a beam dump already in the (debunk) HWSY path for this ghost beam.
