SUMUTE - mute above (or below) a user-defined
polygonal curve with the distance along the curve specified by key header word
sumute <stdin >stdout xmute= tmute= [optional parameters]
Required parameters:
xmute= array
of position values as specified by
the
`key' parameter
tmute= array
of corresponding time values (sec)
... or input via files:
nmute= number
of x,t values defining mute
xfile= file
containing position values as specified by
the
`key' parameter
tfile= file
containing corresponding time values (sec)
Optional parameters:
key=offset Key
header word specifying trace offset
=tracl use trace number instead
ntaper=0 number of
points to taper before hard
mute (sine squared taper)
below=0 =1
to zero BELOW the polygonal curve
Notes:
The tmute interpolant is extrapolated to the
left by the smallest time
sample
on the trace and to the right by the last value given in the
tmute array.
The files tfile and xfile are files of binary
(C-style) floats.
