Dear sac users, I hope you all would be doing fine. I have sac headers of S-wave receiver functions but I want to reverse the time axis of these headers so that it will look like as P-wave receiver functions to compare. Can anybody tell me how to do it ? Your help will highly be appreciated. Thanks, Regards, Mohit Agrawal

Hi all, I 've been using broadband data from IRIS on research and recently encounter a confusing thing about response. I am using the BH* channels of network AZ, and it should be velocity data. I downloaded sac files from SCEC stp. I originally request response file in SEED format, then extracted it to be RESP.AZ.XXX..BHX, the response file. Recently, because I want to confirm the amplitudes in velocity and also in displacement is correct, I went to IRIS SeismiQuery to get the response file… [more]

Hello List, We have just attempted to run sac-101.5c-linux_x86_64 on a machine running 64-bit SuSE Linux Enterprise Desktop 10.3, and are immediately greeted with a floating point exception.

sac helpers please help me I have two questions: 1) why is the behavior of the commands 'p1 rel' and 'ppk rel' different? I can line up waveforms on a pick nicely using 'p1 rel', but when I use 'ppk rel', the same waves align on something different, on b I think. I found a previous post about this same issue back on July 5, 2006, but could not find a response to it. I want to make picks after aligning the waves on another pick. 2) I recently installed 101.5c and now my default xwindow si… [more]
