Dear SAC Users,
I have some sac files where T0MARKER and T1MARKERS are set corresponding to
P-and S-wave arrival times.
But, when I plot my seismograms it does not show "P" and "S" corresponding
to their arrival marks; instead it shows "t0" and "t1".
or, when I list my headers, it shows like this:
T0MARKER = 239.23
T1MARKER = 456.45
but I want it to be like this:
TOMARKER = 239.23 (P)
T1MARKER = 456.45 (S)
How to change this. Your help in this regard will greatly be appreciated.
Regards,

Hi Mukesh,
Pick descriptions are stored in header variables KTn, where n is
0,1,2....9. So, you would change KT0 corresponding to T0 and KT1
corresponding to T1 as follows,
CHNHDR KT0 P KT1 S
Januka.

Here is another way:
SAC> ppk
The output will include AMARKER = 10.464 (IPD0) T0MARKER = 10.704
(ISD0)
put your cursor on the time for your P arrival and enter ipd0 (for a P heading
down with eight 0)
put cursor at your S pick and enter isd0 (for S arrival)
Enter q to exit ppk
SAC> lhpicks
the output will include
AMARKER = 10.464 (IPD0) T0MARKER = 10.704 (ISD0)
