  1. Absi3D 3-D Auto Beam Steer+Interpolate Wed Jul 18 15:48:28 CDT 2007 Can this process be used inside an IF block? UNKNOWN ********** Overview ********** ************************ Parameter Descriptions ************************ Parameter: COMMENT: Name: COMMENT Type in a line of comment. Use up to 60 characters per line. If more than one line is specified, only the first line will show. Default value: "" type in a line of comment related to this process in this job flow -------------------------------------------------------------------------------- Parameter: Header identifying groups Name: grphdr Default value: "NONE " Use MB1 to specify the trace header that marks a group of ensembles. Use NONE for poststack data. -------------------------------------------------------------------------------- Parameter: Inline aperture Name: nxa Parameter is an integer value. Number of allowed characters is 7 Minimum allowed value is 1 Maximum allowed value is 15 Default value: 5 Number of traces in the aperture. Should be an odd number. -------------------------------------------------------------------------------- Parameter: Inline move up

  2. Name: nxm Parameter is an integer value. Number of allowed characters is 7 Minimum allowed value is 1 Maximum allowed value is 15 Default value: 3 Number of traces to move up. Should be an odd number. -------------------------------------------------------------------------------- Parameter: Minimum inline dip Name: pxmin Parameter is a real value. Number of allowed characters is 8 Minimum allowed value is -50.0 Maximum allowed value is 50.0 Default value: -4.0 Minimum dip in the inline direction (in ms/trace). This is the dip from trace to trace within a line. -------------------------------------------------------------------------------- Parameter: Maximum inline dip Name: pxmax Parameter is a real value. Number of allowed characters is 8 Minimum allowed value is -50.0 Maximum allowed value is 50.0 Default value: 4.0 Maximum dip in the inline direction (in ms/trace). This is the dip from trace to trace within a line. -------------------------------------------------------------------------------- Parameter: Inline p taper (traces) Name: lpxtaper Parameter is an integer value. Number of allowed characters is 2 Minimum allowed value is 0 Maximum allowed value is 50 Default value: 3 Enter a taper length in traces. This is the number of extra p traces computed and ramped down to reduce truncation artifacts. -------------------------------------------------------------------------------- Parameter: Crossline aperture Name: nya Parameter is an integer value. Number of allowed characters is 7

  3. Minimum allowed value is 1 Maximum allowed value is 15 Default value: 1 Number of lines in the aperture. Should be an odd number. Use 1 for a 2-D beam steer. -------------------------------------------------------------------------------- Parameter: Crossline move up Name: nym Parameter is an integer value. Number of allowed characters is 7 Minimum allowed value is 1 Maximum allowed value is 15 Default value: 3 Number of lines to move up. Should be an odd number. -------------------------------------------------------------------------------- Parameter: Minimum crossline dip Name: pymin Parameter is a real value. Number of allowed characters is 8 Minimum allowed value is -50.0 Maximum allowed value is 50.0 Default value: -4.0 Minimum dip in the crossline direction (in ms/trace). This is the dip from line to line. -------------------------------------------------------------------------------- Parameter: Maximum crossline dip Name: pymax Parameter is a real value. Number of allowed characters is 8 Minimum allowed value is -50.0 Maximum allowed value is 50.0 Default value: 4.0 Maximum dip in the crossline direction (in ms/trace). This is the dip from line to line. -------------------------------------------------------------------------------- Parameter: Crossline p taper (traces) Name: lpytaper Parameter is an integer value. Number of allowed characters is 2 Minimum allowed value is 0 Maximum allowed value is 50 Default value: 3

  4. Enter a taper length in traces. This is the number of extra p traces computed and ramped down to reduce truncation artifacts. -------------------------------------------------------------------------------- Parameter: Semblance threshold Name: clobber Parameter is a real value. Number of allowed characters is 8 Minimum allowed value is 0. Maximum allowed value is 1. Default value: 0.0 Semblance is zeroed below this value. -------------------------------------------------------------------------------- Parameter: Signal to noise rating Name: swin Selection Choices: Very good ==> 11 point smoothing filter Good ==> 31 point smoothing filter Fair ==> 51 point smoothing filter Poor ==> 101 point smoothing filter Diggity ==> 7 point smoothing filter Sweet ==> 5 point smoothing filter Perfect ==> no smoothing Very Poor ==> no semblance weighting applied Specify the quality of your data. Controls the length of the smoothing filter applied to the semblance weighting. -------------------------------------------------------------------------------- Parameter: Maximum frequency of interest Name: fmax Parameter is a real value. Number of allowed characters is 8 Minimum allowed value is 1.0e-6 Default value: 80.0 This is the maximum coherent frequency (in Hertz) that is of interest in the data. -------------------------------------------------------------------------------- Parameter: Apply the frequency (rho) filter? Name: applyRho Selection Choices: YES ==> Apply rho filter. NO ==> Do not apply rho filter. Default value: 1 --------------------------------------------------------------------------------

  5. Parameter: Length of rho filter Name: lenRho Parameter is an integer value. Number of allowed characters is 5 Minimum allowed value is 5 Maximum allowed value is 10000 Default value: 81 Specify the length of the rho filter in points. The filter is designed in the frequency domain, transformed to time, and windowed to the specified length. -------------------------------------------------------------------------------- Parameter: Window type Name: window Selection Choices: Hamming ==> Raised cosine on a platform Hanning ==> Raised cosine window Blackman ==> Double cosine window Bartlett ==> Triangular window Rectangular ==> No window Half Hamming ==> Rectangle in the center, Hamming on the ends Half Hanning ==> Half Raised cosine window Half Blackman ==> Half Double cosine window Half Bartlett ==> Half Triangular window Choose a window function for the rho filter design. -------------------------------------------------------------------------------- Parameter: Plot the rho filter? Name: plotRho Selection Choices: YES ==> Create filter plots. NO ==> Do not create filter plots. Default value: 1 -------------------------------------------------------------------------------- Parameter: Rekill dead traces? Name: rekill Selection Choices: YES ==> Traces dead on input will be rekilled on output. NO ==> Allow dead traces to come to life. Default value: 1 -------------------------------------------------------------------------------- Parameter: Debug mode? Name: debug Selection Choices: NO ==> Run silent, run deep. YES ==> Print trace flow information.
