Tpow - scales on the time axis
Tpow par= < in.H > out.H
Select a power of t for seismogram scaling out(t) = data(t)* t**tpow
[nt],[nx],[11 usual seismic data t inner
[dt],[dx] samplinginterval
[ot],[ox] [first sample time]
power of time
[1] (default) 1st panel is used for estimating tpow.
When panel=all, all panels are used.
time of the first sample to be used in estimating tpow.
[4.]end of region used on time axis
[unknown] unknown: automatic picking of first
arrivals will be applied to compute the muting parameters
no: data are offset-independent
yes: data are offset-dependent
(km/s) apparent |dx/dt|. muting
before first arrival time will
be applied in estimating the
medians. when no v0 is given
and ofdep is not "no", automatic
picking will be applied
[1] the first trace used for Tpow
the last trace used. For 3-d data,
trace nxmin to trace nxmax are
used on each plane if panel=all.
[0.05] (default) iteration of estimating dtpow stops
when abs(dtpow) < eps.
[2] subsample rate (integer) of time for tpow
estimating
[1] subsample rate (integer) of trace for tpow estimating
[9] window length used for calculating L-1 energy in autopicking
[10.] when L-1 norm of present window exceeds
that of the previous one by
"perc", first arrival is picked
m02 * (.25*tmax)**(dtpow) = m24 * (.75*tmax)**(dtpow)
tpow = tpow + dtpow
where
m02 --- median over (0, tmax/2) of | data(t) | * t**tpow
m24 --- median over (tmax/2, tmax) of | data(t) | * t**tpow
