Hello:
I have a set of Canadian seismograms that I need to remove the
instrument response from. I have converted the seed files to sac files
and extracted the RESP files. I am using the following commands in
SAC:
sac> file.sac
sac> rmean
sac> rtrend
sac> taper
sac> trans from evalresp to none freq .01 .015 2 5
When I use the evalresp file I get the following output:
Nominal Calper not set. Setting Nominal Calper to -999.000000 to
match Wfdisc Calper
Sensor Calper not set. Setting Sensor …

dear All,
we recently moved to ubuntu 64bit our computer used for running some
complex sac macros that generate figures by first creating .sgf file
and then converting it to ps by using sgftops. sac version is 101.4
linux64.
We now observe unrequested straight lines (see attachment) that from
some points in one of the boxes reach the lower left corner.
The problem is not observed when plots are sent to screen by using bg
X instead of bg sgf.
sgf files are normally 2-3Mbyte large.
Any…

Hello,
Is there any way to detect a non-number value (like inf and nan) in an if loop?
I couldn't find any references to this in the manual.
All versions below are simply ignored by sac:
mtw %min %max
rms to user0
setbb sta &1,user0
*** doesn't work:
if %sta eq inf
message "***** not a number ******"
endif
*** doesn't work:
if %sta eq "inf"
message "***** not a number ******"
endif
Note, this works:
if %sta eq 0
message "***** detected zero ******"
endif
Thanks,
Igor

A participant in our USArray Data Processing short course this week discovered that SAC will happily "interpolate" to a larger DELTA value (fewer samples), and apparently does so without anti-alias filtering.
Would you consider building in an error message if the DELTA given to "interpolate" exceeds the DELTA in the SAC files in memory?

Dear SAC-users:
I am using SAC for seismological analysis recently. However, I got some
problem about HYPO format using OHPF with sac101.4. I piked/marked the phase
after opening the OHPF and OAPF, but the result is different as follows:
case1: GJM IPU0 11 3 9 24663.00 0 0.0 (OHPF)
case2: -12345 GJM 90.00 90.00IPU0 2011 68 2 46
2.06 -4171 M (OAPF)
In case1 the second of the P arrival is 63.00, while in case2 that is 2.06.
What does the last four d…
