Chuck,

Yes, in this case it seems to be the eSignal data. For some reason, 
I'd thought that to be THE most reliable...

The problem is that Yahoo! data for TONE only goes back to October 
2002, so the corrupt data from eSignal before that date remains in 
the database. I guess I'll have to delete all my data and re-build 
using Yahoo!(CSI)!!
