Hiii,
I am a beginner to SAC and I am trying to pick and display phases on
seismograms using PPK. I will really appreciate some help on this.
SAC>read filename
SAC>p1
SAC>ppk
# using curser, I click on a point and press p to show P-wave pick, then i
press q to get #out of ppk
SAC>p1
but now the plot shows IPUO instead of just P and it shows ISUO instead of
S. I tried assigning t0, t1 to phase picks, and then trying to change the
name using PICKPHASE, but for some reason it doesn't work (or maybe I am
using the wrong command)
SAC>pickphase t0 P
SAC>p1
please please please help :( :(
How do I get SAC to display just P or any phase name or just time picks (no
phase name) ?
Thanks.
Regards,
Avinash

Hi,
You can store phase picks in Tn, and phase names in KTn.
SAC> r seis
SAC> ppk
# mark P phase as T0, and S phase as T1
SAC> ch kt0 P kt1 S #### change the name of phase
pick
SAC> wh
SAC> p1
SAC> q
In fact, in ppk, if you press the p to mark P phase, the pick is stored in
A, and phase name stored in KA.
Then press s to mark S phase, the pick is stored in T0, and phase name
stored in KT0.
