DESCRIPTION

     wax reads seismic data and computes one of  several  complex
     attributes  within  a  user defined window or running window
     analysis.

     wax gets its data and parameters  from  command  line  argu-
     ments.  These  arguments specify the input, output, starting
     record number, ending record number, starting trace  number,
     ending  trace  number,  and desired complex signal attribute
     and window type.

  Command line arguments
     -N ntap
          Enter the input data set name or file immediately after
          typing -N unless the input is from a pipe in which case
          the -N entry must be omitted.  This input  file  should
          include the complete path name if the file resides in a
          different directory.

     -O otap
          Enter the output data  set  name  or  file  immediately
          after typing -O.  This output file is not required when
          piping the output to another process.  The output  data
          set  also  requires  the full path name (see above). In
          the case of a running window analysis (-run) the output
          will  be  on the order of the size of the input data as
          opposed to a single attribute map when no running  win-
          dow is enabled.

     -rs rs
          Enter the desired starting record number.  If no entry,
          program assumes first record in data set.

     -re re
          Enter the desired final record number.   If  no  entry,
          program assumes last record in data set.

     -ns ns
          Enter the desired starting trace number.  If no  entry,
          program assumes first trace in each record.

     -ne ne
          Enter the desired final trace  number.   If  no  entry,
          program assumes last trace in each record.

     -thresh thsh
          Enter a threshold to limit  the  attributes  associated
          with  response  frequency and amplitude. This threshold
          is a decimal multiplier ranging from 0.0  to  1.0.  The
          program  multiplies  this  threshold  times the maximum
          trace envelope; then it computes a  response  value  at
          each  sample  where the trace envelope peak exceeds the
          product of thresh*maximum envelope value.   (default  =
          0.15).

     -win win
          Enter a window length for  analysis.   Default  is  the
          length of the input data.

     -abs Enter the command line  argument  '-abs'  to  take  the
          absolute value of the input time series prior to attri-
          bute calculation.

     -run Enter the command line argument '-run' to enable a run-
          ning window analysis.

     -avg Enter the command line  argument  '-avg'  to  calculate
          average.

     -median
          Enter the command line argument '-median' to  calculate
          median.

     -area
          Enter the command line argument  '-area'  to  calculate
          the area.

     -sd  Enter the command  line  argument  '-sd'  to  calculate
          standard deviation.

     -sum Enter the command line  argument  '-sum'  to  calculate
          time series sum.

     -max Enter the command line argument '-max' to find the max-
          imum value.

     -min Enter the command line  argument  '-min'  to  find  the
          minimum value.

     -range
          Enter the command line argument '-range'  to  find  the
          range.

     -skew
          Enter the command line argument  '-skew'  to  calculate
          the skew.

     -kurt
          Enter the command line argument  '-kurt'  to  calculate
          the kurtosis.

     -quadrature
          Enter the command line argument '-quadrature' to caclu-
          late the quadrature.

     -carrier
          Enter the command line argument '-carrier' to caclulate
          carrier.

     -envelope
          Enter the command line argument '-envelope'  to  caclu-
          late the envelope.

     -envelope_skewness
          Enter the command line argument '-envleope_skewness' to
          caclulate the envelope skewness.

     -envelope_rise
          Enter the command  line  argument  '-envleope_rise'  to
          caclulate the envelope rise.

     -inst_freq
          Enter the command line argument '-inst_freq' to  caclu-
          late instantaneous frequenc.

     -inst_phase
          Enter the command line argument '-inst_phase' to caclu-
          late instantaneous phase.

     -inst_band
          Enter the command line argument '-inst_band' to  caclu-
          late instantaneous band.

     -zero_phase
          Enter the command line argument '-zero_phase' to caclu-
          late zero phase.

     -ninety_phase
          Enter the  command  line  argument  '-ninety_phase'  to
          caclulate ninety phase.

     -response_length
          Enter the command line argument  '-response_length'  to
          caclulate response length.

     -response_amp
          Enter the  command  line  argument  '-response_amp'  to
          caclulate response length.

     -response_freq
          Enter the command  line  argument  '-response_freq'  to

     -V   Enter the command line argument '-V' to get  additional
          printout.
