Thread: help with response

Dear All,
I am trying to remove the response from the waveform
I
downloaded from IRIS
my platform is GSAC Under CYGWIN,

I did the following:

1.Downloaded RESP file for the station from
RESPONSES
folder of IRIS
2. I used the following shells:
A.
#!/bin/sh
evalresp EIL BHZ 1996 200 .01 10.0 100 -f
RESP.GE.EIL..BHZ -u vel \
-n GE -t 00:00:00


sacevalr -DEMEAN True -TAPER True -FREQLIMITS 0.01
.02 5.0 20.0 \
-AMP AMP.GE.EIL..BHZ -PHA PHASE.GE.EIL..BHZ \
-SACIN GE.EIL..BHZ.R.SAC -SACOUT GE.EIL..BHZ.Sac

and with other variant:
B.
#!/bin/sh
evalresp EIL BHZ 1996 200 .01 10.0 100 -f
RESP.GE.EIL..BHZ -u vel \
-n GE -t 00:00:00


sacevalr -DEMEAN True -TAPER True \
-AMP AMP.GE.EIL..BHZ -PHA PHASE.GE.EIL..BHZ \
-SACIN GE.EIL..BHZ.R.SAC -SACOUT GE.EIL..BHZ.Sac

resulting file I got an empty disp
window with nothing in it , after exiting I found
the
following message:
GPV: nper = 0 check aa,bb,cc
NUM_PERIOD 0

4. I examined the resulted file with pltsac CMD it
was
ok
