Hello Can you help me with the correct syntax for Wiechert instruments response correction in SAC. Who can I know which period, damping and magnification it's the algorithm using by default? I try this sintax : "transfer from WIECH freeperiod 'To' magnification 'Am' damping 'e' " And I also tried whitout specify the constants and the result its very similar. Thank you all in advance Raúl Daniel Corona UNAM. Geophysics Institute |
