Re: lacking GCARC, EVDP, EVLA, EVLO header infornmation and relative time
2010-08-27 18:10:44 - 2010-08-27 21:52:20
Hi Rob, All of the files are lack of header informations. You can start with the smallest one--File:bh1990-1992.26595.seed 1280 KB 8/25/10 3:50:00 PM I used JWEED 3.0 to get seed files and "rdseed -dpf" or "rdseed -d -o 1 -f" "rdseed -df" to extract SAC from seed. SAC version is Version 101.3. Actually, I think that the header should have been completed, right? There may be something wrong with the way I proceed(I used JWEED to generate breq_fast request), which leads to the lost of he… [more]

lacking GCARC, EVDP, EVLA, EVLO header infornmation and relative time
2010-08-26 18:06:06 - 2010-08-26 22:54:08
Hi all, I am not sure whether I have successfully sent this email before but I really need someone to help. My SAC files 1) lost GCARC, EVDP, EVLA, EVLO header information; 2) time appears to be absolute instead of relative(B = 0.000000e+00) when I used "rdseed -dpf" to extract SAC from seed. What should I do to get those above header informations? I used JWEEDv3.12 to get the seed files and rdseed 5.0 to extract. Thank you in advance!! Panxu

However, I cannot find the source code of the SAC-IO library in any (sub)-directory. I need it to re-compile that library code on my PC in Windows, for linking it to FORTRAN codes I have been developing. The SAC (101.4 version) installation was succesful on Linux and the software is working properly. I could also succesfully link the BINARY version of the… [more]
