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.
[o1]: 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
