Re: problem with interpolation - Arthur Snoke - 2011-01-04 23:00:50

The message below has been identified as a bug in 101.4 and I can
confirm this behavior using the ohpf command on my system. This came
about during the conversion from 32 to 64 bit version of sac.
If you require this patch before the release of version 101.5, please
contact me directly. This fix will be made available in version
101.5, coming out next year.
Thank you for reporting this bug to the sac-help mailing list.

Hello,
Anybody knows if there is any problem related with the recent ubuntu
kernels and SAC? It seems to be a bug with Time interpretation when
using ppk with an OHPF file opened. Last months ago I was working with
SAC version 101.3b and everything worked properly. But I recently
actualized my ubuntu pc and this strange ppk image (see the attached
file) appears. I obtain the same strange figure when using SAC version
101.3b and 101.4, so I think it is not a SAC problem but a linux one, a…

Hi all,
I am working with seismological data in sac format and I am
interested in bringing the transmission responses of data to the tau-p
domain. I think SAC software has not this function.Nevertheless, one
possibility is to use SU software from Colorado School of Mines to do
that. My problem is:
How can sac data be transformed into a compatible SU format (like segy)?
Thanks in advance for any suggestions or comments and best regards,
John Gonzalez

Hi SAC users!
Half of year ago I tried to read CSS files under 101.3b (see
http://www.iris.washington.edu/pipermail/sac-help/2010-March/000705.html).
Today I tried to read CSS data again.
Now I have sac version 101.4b but nothing changed, after command readcss I
see usual:
SAC> readcss ./test_val.wfdisc
No wfdisc file(s) found in the specified directory
ERROR 1301: No data files read in.
or big fault:
SAC> readcss ./test_val.wfdisc
No wfdisc file(s) found in the specified directory

Hi SAC Users,
I am using a rotational sensor with a transfer function
W(f) = A*s^2/[(s - p1)*(s - p2)*(s - p3)*(s - p4)*(s - p5)],
where:
A=6727500 V/(rad/sec)*Hz^3;
p1 = 0.02 Hz
p2 = 0.04 Hz
p3 = 23 Hz
p4 = 65 Hz
p5 = 90 Hz
I would appreciate any help in converting data that is currently in counts
to data in radians or radians per second.
Thanks.
