Mute - Mute a SEP77 dataset
Mute par= < in.H > out.H
1.45 ; outer mute velocity
0.0 ; start time of (hyperbolic) outer mute
0.25 ; linear mute time ramp in seconds.
0. ; Scale(t>Tmute+tramp) = 1.
0 ; gain trace data by t**tpow
0 ; scale offset (x) traces by (x/xmin)**xpow
0 ; no trace balancing 1 ; trace balance by sum of absolute values 2 ; trace balance by rms amplitude value 3 ; trace balance by trace energy (sum of squared values)
0 ; no weighting 1 ; Jon's weight by 1/(t+xmax/vmute), like dividing by the number of traces: radial weight by r / ( 1. + (r*r)**2 ) r = r0 * x / (t * vmute) r0 = sqrt( sqrt( drop - 1. ) )
[10.] good till
0 ; no taper N ; linear taper on the last N traces at either end of gather.
list ; list of trace numbers to kill (first trace no. is 1)
end of trace ; start time for end of data mute
0.25 ; ramp length at end of trace
Apply linear outer mute to gather + preprocess for velocity analysis
