[SAC-HELP] taup_setsac errors in setting theoretical arrival times of phases

[Arthur Snoke]

As noted in the traveltime help file that comes with version 101.4, 
traveltime in IRIS/SAC does not work.  although not directly related to 
your quesiton, I would appreciate it if anyone has succeeded in getting 
something like the iaspei-tau program ttimes working in C.  If so, please 
send me the source as I would like to fix at least that part of the 
sss/traveltime command.

What you have done is very similar to what is suggested in the SAC help 
file <http://www.iris.edu/software/sac/commands/sss.com/traveltime.html> 
escept you leave out the sc and the -1 in P-1.  On my mac (OS 10.6) I 
reproduced the results in the help file with a line like yours:

SAC> taup_setsac -evdpkm -ph P -verbose test.z
test.z
Using gcarc: 3.3574646
test.z searching for P
P: P END
0 1 2 3 4 5 5 4 3 2 1 0
minRayParam=254.33137581441554 maxRayParam=1098.448275862069
minDistance=0.0 maxDistance=98.39983407057541
-----------------
test.z 5 arrivals found.
test.z phase found P -> t0, travel time=64.63958
test.z phase found P -> t0, travel time=64.35809
test.z phase found P -> t0, travel time=60.571896
test.z phase found P -> t0, travel time=60.38368
test.z phase found P -> t0, travel time=53.694054
SAC> r test.z
SAC>  lh amarker t1marker

   FILE: test.z - 1
  ------------

      amarker = 10.47       t1marker = 10.494           (P)

As you get the same error outside of SAC, it sounds like your immediate 
problem is with the taup on your system.
