Hi People,

 The muon data quality is used by run, by lum'y block, and by event.
 The info on runs is in the Run Quality Database. Use "good" or 
 "reasonable" runs. If you use ".not.bad" you will pick up "special"
 runs which may have wierd conditions, for instance, magnets off, or 
 test triggers.

 Information about the quality of lum'y blocks is available in SES files. 
 This is intended to cover the latency loophole in monitoring.

 Information about the event quality is found in flags in the DST's
 and TMB's.  It is concentrated on readout errors such as out-of-sync or
 checksum problems.

 The standard for p10 through p14 is the Run Quality. 

 There are plenty of details in the talks listed near the bottom 
 of the data quality link.
