Guralps page on Poles and Zeros
Guralp also has an automated instrument response retrieval service. Email
caldoc@guralp.com with an instrument serial number (e.g. T6197) as the
subject to the most up to date response information for that instrument.
Sensitivity data are available at sensor-gains.txt
N.B. Sensitivity data change following instrument repair.
Therefore users must be aware that their the sensitivity relevant
to their deployment is determined by the deploy/pull-in dates
calvals.txt file for Guralp's Scream software is here
 
FIR Coefficents and TTL values are available here
