Dear all,
I seem to have lost my old macros!
I am looking for two types of macros one that are used in routine picking of phase arrival times and the second in the extraction of phase and and header information from picked data sets, if you don't mind sharing your macros?
basic, simple, sophisticated will do!
Kind regards,

Dear Montu
The best way is the manual web pages : http://www.iris.edu/software/sac/manual.html
On the other hand, the SAC team should give the manuals as zipped file for off-line usage.
best regards

Hi,
please give more detail. Do you want to find poles&zeros of an instrument? (you may contact its dealer)
Or, do you want convert known poles&zeros for SAC-transfer usage?

Dear Mr. Gogoi,
My students like Zhagang Peng's SAC tutorial:
http://geophysics.eas.gatech.edu/classes/SAC/ . And don't forget the
SAC tutorial that is part of the documentation:
http://www.iris.edu/software/sac/manual/tutorial.html
Hope that helps.
Best Regards,
Derek

Hi All!
I am using a SAC file download to wilbert, but it have IDEP = Unkwon. I need
that IDEP = velocity, then I try to remove the instrument responses.
First I download RESP file from IRIS RESP Service.
I used this RESP file and command trasfer, but I obtain this in screen.
SEISMIC ANALYSIS CODE [06/06/2005 (Version 100.1)]
Copyright 1995 Regents of the University of California
SAC> r 2009.302.11.02.28.3950.GB.DYA..BHZ.R.SAC
SAC> trans from evalresp
Extracting evresp response for DYA, BHZ...
Station (DYA ), 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.
Could anyone explain me the error? or Could anyone explain the correct form
to use command trasfer?, please
Regards,
Astrid L?pez
