[wxqc] Analysis

[Sam Drinkard]

Out of curiosity, can someone tell me how the analysis graphs are 
generated, or which station(s) is/are used to set the standard?  Doing 
comparisons of DNL/AGS/Me, I see quite a bit of change of the analysis 
when switching from my graphs over to DNL or AGS.  Is the station which 
provides the analysis data constant, or does that particular aspect of 
the QC change daily.  For clarification,  I'm talking about the graphs 
that Philip's software generates.
