bdcn - BSU program which peforms a spiking deconvolution (by profile or trace mode)
bdcn [ -h | infile | tmin | tmax | mpts | stabf | iprof | imode ]
Basic Seismic Utilities (BSU) spiking deconvolution. One may select either a profile mode (one filter for the entire data set) or trace mode (each trace has a designed filter). One may also select prediction instead of deconvolution.
Options
|
-h |
Online help giving details on command line arguments | ||
|
infile |
Input file name | ||
|
tmin |
Minimum time for the design gate | ||
|
tmax |
Maximum time for the design gate | ||
|
mpts |
The number of points in the one sided auto-correlation, and in the decon filter. | ||
|
stabf |
Stability factor realized by adding a fraction of the zero lag auto-correlation to itself. | ||
|
iprof |
Switch to select mode of operator design |
0=trace mode (one operator for
each trace)
1=profile mode (one operator for entire profile)
|
imode |
Switch to select mode of operator design |
0=Spiking Decon (prediction
error mode)
1=Prediction mode (unit prediction distance)
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
bdcn twav.seg 0. .5 51 .01 1
File twav.seg is processed with spiking deconvolution. The design gate for the autocorrelation begins at tmin=0.0 seconds, extends to 0.5 seconds. The operator will have 51 points (length in samples). The stability factor, 0.01, will be added to the zero lag autocorrelation. The data will be processed in profile mode (one filter for the entire data set).
bdcnxxxx.seg
Output, deconvolved input data. Named according to convention (first 4char bdif, the next 4char are the first 4char of the input file name, suffix .seg)
bdcnfltr.seg
Output, deconvolution operators used on each trace.
standard output
produces a progress bar
bdcnxxxx.lst

bhelp(1), xcor1(3), cross(3), eureka(3), fold(3), conv2(3)
No known bugs. Current version uses E.A.Robinson’s routines (cross,eureka,fold).
