Dear to all,

When removing the instrument response from the data I get some error
messages that I have not been able to find what are they due to.

These are:
Calper is not available. Cannot tell if response is normalized, so transfer
function will be used without scaling.
Calib is not available. Cannot tell if scale factor has been applied on
input, so transfer function will be used without scaling.
        Waveform multiplied by 1.000000 after deconvolution.

Another error message in some data are:
WARNING: FIR normalized: sum[coef]=9.781101E-01; US AMTX  LHZ


I appreciate if someone could tell me what is it due to, how can I avoid
these errors and, the most important, in what do they affect the
deconvolution.

Thank you in advance.
