Hello everybody, I am trying to set some times in a SAC header. So far I did the following: ch NZYEAR 2000 NZJDAY 100 ch NZHOUR 13 NZMIN 10 NZMSEC 0 NZMSEC 0 Although some of these changes do not appear with the 'lh' command (only when specifically referencering a header variable (e. g. 'lh NZMIN') I assume that this works fine. However, I would like to put a time string into the header. This variable is called KZTIME, as far as I understand. Since this is an alphanumeric variable, I assume... [more]
Dear Scientists, The problem that the rotation is not succesfull is that because the sac files you use do not have the right header. This always happens when you use miniseed data. The problem with seed data does not exist!!

I am using some SAC applications that have been developed elsewhere and work on SunOS Unix. I am running sac2000 on SunOS 5.8. I have a problem when a macro issues a "system command" (sc) that needs an escape character before a character that would otherwise be interpreted by SAC. The command that is passed to Unix does have the escape character removed but it is not interpreted correctly by Unix. For example, the following command returns an syntax error for the awk portion of it: ... [more]
