Dear Sac_help users,
I have some sac data from HYB station located on Indian Shield at Hyderabad. OMARKER doesn't seem to be set at correct value. I requested seed data file and extracted sac data using rdseed using summary file to put the event information in the sac headers.
I am not sure what could be the problem. Any suggestion regarding this?
NPTS = 87180
B = 3.000000e-04
E = 4.358951e+03
IFTYPE = TIME SERIES FILE
LEVEN = TRUE
DELTA = 5.000000e-02
IDEP = UNKNOWN
DEPMIN = -8.237908e+02
DEPMAX = 9.231357e+02
DEPMEN = -6.515828e-01
OMARKER = 67963
KZDATE = JAN 08 (008), 2000
KZTIME = 01:27:17.044
KSTNM = HYB
CMPAZ = 9.000000e+01
CMPINC = 9.000000e+01
STLA = 1.741700e+01
STLO = 7.855300e+01
STEL = 5.100000e+02
STDP = 0.000000e+00
EVLA = -1.048570e+01
EVLO = 1.121649e+02
EVDP = 2.000000e+00
KHOLE =
DIST = 4.815776e+03
AZ = 3.095449e+02
BAZ = 1.274029e+02
GCARC = 4.326407e+01
LOVROK = TRUE
NVHDR = 6
NORID = 0
NEVID = 0
LPSPOL = FALSE
LCALDA = TRUE
KCMPNM = BHE
KNETWK = G
MAG = 5.300000e+00
Any help will really be appreciated.
Thanks and regards,

Hi Sachin,
I didn't see the IZTYPE header so that I guess you haven't entered the origin time. If you intend to make OMARKER be zero to have the travel time, all you need to do is to give the event origin time in the SAC header variables:
SAC> ch O GMT year jday hour min. sec. msec
SAC> ch allt ( 0.0 - &1,O ) iztype io
SAC> wh

Hi Sachim,
What is origin time of event?
what would be the correct value of OMARKER for you?
