Hello all,
I'm trying to compile a fortran77 program (getsnr.f) which includes some
SAC routines:
PROGRAM getsnr
C
INTEGER npts, nerr
REAL*4 rftn, beg, del, snr
CHARACTER nom*50
C
CALL getarg (1,nom)
CALL rsac1 (nom,rftn,npts,beg,del,1,nerr)
CALL getfhv ('user0',snr,nerr)
C
WRITE (6,*) snr
C
END
As you can see, the code is straightforward. Its only goal is to get the
signal to noise ratio contained in the header of sac fil…

Hi all,
I work with SAC files for located events with OMARKER set to 0, and so the
KZDATE and KZTIME are the origin time parameters, which I extract and use
for data processing.
Some of my SAC files have slightly different origin times (located using
different numbers of stations), and I want to fix this so it's consistent
across all the sac files for a particular event. And so that OMARKER is 0
and KZDATE and KZTIME reflects the absolute origin time.
Any ideas on how to do this?

Dear,
I have downloaded data from many events. I need to rotate and remove
instrument response of all of them. I am using sac.
1) Some of the events have the components called BH1 and BH2 (or BH2 and
BH3) instead of BHE and BHN. To rotate, I need to know which one is BHE and
which one BHN. For that, I watched the header information looking for
CMPAZ=90 - CMPINC=90 for East component BHE, and CMPAZ=0 - CMPINC=90 for
North component BHN.
The problem was that in some cases the numbers of the CM…

That would definitely work. I am just wondering what is this error about,
since I never faced this issue on a different compiler (ifortran), and now
I'm running the same script with same data on gfortran and with this error.
Best,

Which is true what you are saying in this case. However, even when I use a
different station with a different instrument response, I'm getting the
same error.
Again, this error is appearing in gfortran compiler. However, I never ran
into this error on my previous compiler (i…

export PATH=${PATH}:${SACHOME}/bin
export SACAUX=${SACHOME}/aux
Then, I modified my .bashrc file and added the following lines
export SACHOME=/home/deprem/soft/sac
