Hi SAC users,
I am writing a simple script to remove the instrument response by using
SAC (Version 101.2).
When I was testing the SAC's transfer command, I got this message:
SAC> r 2006.319.11.18.29.3500.KN.ULHL..BHZ.R.SAC
SAC> transfer from evalresp
Extracting evresp response for ULHL, BHZ...
Station (ULHL ), Channel (BHZ )
Waveform multiplied by 1.000000 after deconvolution.
The SCALE field is properly set in the SAC header, but for some reason the
waveform is multipl…

Hi
I would like to use the type evalresp to compute the signal corrected
from the instrumental response (files provided by rdseed).
What is the IDEP value which should be insered in the header to say that
I have raw data? Presently in my data IDEP is not defined
I have accelerometric data.
What is the result on accelerometric data of the command
transfer from evalresp to none
What is the result of
transfer from evalresp to acc
the amplitudes are different (even after removing the high fr…

Dear All,
I am writing an instrument response correction script. I set stations' name
and event seperately. It works for "read" in SAC, but not for trans
polezero. Any suggestion on this one? Thank your for your time and effort.

set STA = "GAC"
set EVENT = "200411150906"

I'm trying to install SAC in my Linux machine (Fedora9).
I have problem when I run the SAC command.
If anyone has had any similar problems installing,
I would be grateful for advice.

I copied the Do Loop macro for particle motion plots from the Do Loop
Examples contained in the MACRO Section of the SAC Manual, and have found a
problem See Macro followed by explanation below:
READ ABC
SETBB TIME1 0
DO TIME2 FROM 2 TO 10 BY 2
XLIM %TIME1 $TIME2
TITLE 'Particle Motion from %TIME1 to $TIME2$'
PLOTPM
SETBB TIME1 $TIME2
ENDDO
There are four variables in the macro
Time1 The starting value for XLIM
Time2 The ending value for XLIM
Upper limit of macro processing

Hello SAC users,
I have a dataset from a station that was NOT placed perfectly level -
e.g. the sensor was placed on a ledge that had a little bit of tilt,
such that Z is not perfectly up/down, and N + E have some down or upward
component in the data. I'm now trying to analyze that data, but have
yet to find a good definition of cmpinc in the manual (all it says is
"Component incident angle (degrees from vertical)"). CMPINC has no
inherent orientation (like CMPAZ, from north, and look…
