[RASMB] SedVel60K centerpieces

[John Correia]

RASMBers
 
To my knowledge I am the only person to report noisy scans with the SedVel60K centerpieces - we suspect a timing issue in the XLA that only manifests itself with the narrower sectors - its worse at low radius than high is the evidence for this - and in fact we are working on a delay calibration issue on my machine as I write this.  CAMIS is also replacing the centerpieces to be sure they are not a defective batch.  So rather than judge the centerpieces on apparently one report, how about some data.  How many labs successfully have used SEDVEL60K centerpieces? How many labs have experienced timing or noise issues with the SEDVEL60K centerpieces?
