Dear Friends, I read sac data and draw by plotpk p 1 then I pick p and s arrival on the data. But I would like to save picked data to the SAC data header. I mean When I open the data after I save even if I close the session of SAC, I would like to see the picked phases on the waveform. Could you tell me How can I do this. Regards...

Hello Murat, after you read a file into SAC, you can use the command SAC> listhdr (or SAC> lh ) within SAC, which lists all existent header values. In case you're only interested in a particular parameter, you need to find it's header name, e.g. "stla" & "stlo" for station latitude & longitude, then it will print only these parameters. Good luck, Eva **************************************************** Eva-Maria Rumpfhuber University of Texas at El Paso / University of Oklahoma 81... [more]

Dear List, I am using rdseed to extract SAC files from seed files: rdseed -f x.seed -d -z 3 -b 2000000 This works fine, except for the Arrival Picks, they don't make it into the sac header. Picks are stored int he seed file and I can see them with: rdseed -f x.seed -c # Event phases: B072F03 Station id: ABC B072F06 Phase arrival time: 2005,003,19:32:59.0299 B072F10 Phase name: SG I could read out this outp...
