From snoke at vt.edu Thu Feb 2 15:30:13 2012 From: snoke at vt.edu (Arthur Snoke) Date: Thu, 2 Feb 2012 18:30:13 -0500 (EST) Subject: [SAC-HELP] SAC v101.5c now available through IRIS Message-ID: Version 101.5c of SAC is now available by request from IRIS DMC . This release fixes some bugs found in v101.5 -- no new features. A description of the modifications are given in CHANGES ()and in HISTORY (). Version 101.5b was sent to IRIS in mid-January, but because of inclement weather it was not on the IRIS Web site for a few days. By that time, a couple of messages sent to sac-help brought to our attention errors that had not ben fixed, so no announcement about v101.5b was sent to the listservs. If you requested and received v101.5b from IRIS, we recommend you replace it to v101.5c. We apologize for any inconvenience. There are binary distributions for Oracle Solaris, Linux (32 bit and 64 bit), and Mac OS X (PPC 32 bit, Intel 32 bit, and Intel 64 bit). You can also request the source code and create a build of your own. SAC can be run on Windows machines running Cygwin. For licensing reasons IRIS cannot provide a Windows Cygwin binary distribution. Prior to v101.5 IRIS provided a separate source distribution for Cygwin, but recent releases (starting with v1.7) can build on Cygwin with the same source distribution as the other platforms. The most up-to-date SAC Users Manual can be accessed online at .

For a signal (a 5.4 Mw earthquake in central Asia: 1996/01/09, centroid. time: 06:27) approaching YELLOWKNIFE array with bearing (azimuth) of 9.7 degrees (back-azimuth: 344.7 degrees), I ran the following command for all vertical components of the event read into SAC: BEAM B 344.7 V 15 EC 33 6.0 C 0. 0. 0. W beam The velocity of 18 Km/s is what I have calculated from the P slowness of 5.9 s/deg. The resulting 'beam' is not even so good if individual files are stacked with zero delay. Furthermore, it is shifted about 10 seconds to the left. Can anyone shed some light on this? SAC manual is really not a big help on this issue. Thank you in advance, Alireza -------------- next part -------------- An HTML attachment was scrubbed...

The options for "transfer" will depend on the format in which the calibration information is provided. See "help transfer". Regards, Sheila Peacock.
