I have been asked about sensor calibration. For my thoughts, please  go to 
_http://www.seismicnet.com/psnlist/index04.html_ 
(http://www.seismicnet.com/psnlist/index04.html)  to  see my letter on the subject, submitted on Tue. 13 
Jul 2004 19:33:44 GMT. I have  used both the methods described there for my own 
sensors.
 
Cheers,
