Mute - Mute a SEP77 dataset
Mute par= < in.H > out.H
[1.45]: outer mute velocity. 0.0: Special case - Flat mute.
[vmute]: vmute as a function of space.
[0.0]: start time of (hyperbolic) outer mute
[tmute]: tmute as a function of space.
[0.25]: linear mute time ramp in seconds.
[0.0]: 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
