    Dear Thulasiraman,

    Your process is correct, only there some importante details.

    1) Your sensor seems a gephone with corner frequency at 5 Hz , so 5 Hz high pass.
    in this scenario your freqlimits are wrong, you can use 6 10 40 50 for example.

    2) Your command transfer from polezero subtype SAC_PZs_YA_LOT1 to vel freqlimits 0.001 0.1 40 50
    i will change to vel —> to none and also change the freqlimits.
    if you do to vel, you obtain velocity, but i do not know if it is that you want

    i will use: transfer from polezero subtype SAC_PZs_YA_LOT1 to none freqlimits 6 10 40 50
    to obtain displacement.



    HTH,

    Milton
