Hello all, Some days ago I requested seed data using JWEED software and then used rdseed to extract SAC files. I also used summary file to put event information into sac headers while extracting the sac files from seed using rdseed, I am using rdseed 5.3.1. But it seems to me that OMARKER time in these headers is not at right place. To give you an example. SAC> lh FILE: 2010.365. - 2 ----------------------------------------------- NPTS = 60400 … [more]

Hi All, I just installed sac-101.6a-mac_x86_64.tar.gz on my mac running OS 10.10.1, but when I try to fire it up, I get this error: [derek@Dereks-MacBook-Pro-3:/usr/local/sac/bin]$ ./sac dyld: Library not loaded: /usr/X11/lib/libSM.6.dylib Referenced from: /usr/local/sac/bin/./sac Reason: image not found Trace/BPT trap: 5 There is no /usr/X11/lib directory on my computer. Does this mean that there's no sac binary that yet runs on Yosemite? Thanks, Derek

The URL for the manual that is up to date is <>. A quick summary of the changes can be seen from an updated paragraph in the README file: * If you need help ... --------------------------------------------------------------------------- 1.

Dear Sir I have a local event recorded by 4 stations that have different sampling frequencies, are 20 Hz and 25 Hz.Therefore I set a new sampling rate to uniform sampling frequency. Previously I checked the maximum frequency signals are recorded by the stations, the maximum frequencies are12 Hz. Then, I decided to choose 25 Hz, given that the minimum sampling frequency is twice the maximum frequency recorded by the station. In this case, I think the seismometers with a sampling frequency of 20… [more]
