Hi,
Does anyone know if you have to use separate PZs files when you are
deconvolving the instrument from BH? data versus HH? data? if the gain
remains the same, can we use the same PZs file by manually changing the
channel code? Is the assumption that the normalization factor remains the
same going from BH? to HH? accurate?

Many thanks !

Januka.

    Hi Januka,

    Response files and PZ files depend of frequency, so
    is not the same calculations at 20 (BH) that 100 (HH)
    channels.
