Does anybody know if it's possible to import arrival picks from seed
files to sac files using rdseed conversion software?? Thanks a lot. Despina

    Hello Despina,

    While it is technically possible for SEED volumes to contain event information including phase arrivals these SEED data structures are very rarely used, consequently the rdseed program does not do anything with them. There is also the possibility to have phase arrivals (usually automated picks) embedded within the data streams themselves but these are also not considered by rdseed when converting data to SAC.

    Hi Despina,

    You could try using the Taup Toolkit, which has a utility to add specified
    phase arrivals to the sac header values. It is beta, but it could be worth a
    shot.

    cheers,
    Andrew

      Dear All -

      See also the TRAVELTIME command in SSS to add time picks from radially symmetric models:

      TRAVELTIME [MORE] MODEL string [DEPTH depth]
      [PICKS n] [PHASE phaselist]
