Thread: Is it possible to force trans + evalresp to use un-calibrated scale factors?

Hi everyone,

I am running the following deconvolution to remove the station
response from a record and transform it into a pure velocity record
in order to compare it with synthetics:


trans from evalresp fname 021294B/RESP/RESP.TS.PAS..BHZ to vel freq
0.001 0.002 1.0 2.0
Using response from user-specified file: (021294B/RESP/
RESP.TS.PAS..BHZ).
Extracting evresp response for PAS, BHZ...

Station (PAS ), Channel (BHZ )
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.


As there is no calibration information in the RESP file derived from
rdseed (number of calibrations = 0) evalresp seems to have decided
not to trust the constants. Is there any way to get around this?

Cheers,

Alessia
