Greetings,
I am trying to deconvolve the instrument response but need poles and zeros
files corresponding to them. Does anyone know where I could get them from?

Thank you.

Januka.

    Hi Januka-

    You can generate SAC poles and zeroes files from IRIS DMC's dataless
    SEED (station metadata) files using our 'rdseed' tool.

    Please refer to this web page on requesting dataless SEED from IRIS
    DMC:
    http://www.iris.edu/data/dataless.htm

    You can get our rdseed tool from here:
    http://www.iris.edu/manuals/#rdseed
    If you use Windows, then try Jrdseed instead:
    http://www.iris.edu/manuals/#jrdseed

    Basically, you read in the dataless file as input, select SAC as the
    output format, and when it asks to output Poles and Zeroes, you say
    yes to that. You should get a bunch of PZ files as a result.

    Hope that helps,

    -Rob
