GENWAV

The output file earth.crv generated by DISPER ( 9.2.6) can be used as input to the program WAVES which will compute a synthetic Rayleigh wave only seismic data profile. This program, genwav, is used to interactively build a namelist file for program WAVES (see 9.2.8).
IMPORTANT: The tmax and sample interval must agree when running gendis and genwav so that frequency sampling matches. The following is a log of an example run of this interactive program.

 genwav
   enter name of namelist file (40 char)
   Example: waves.d
waves.d
   enter name of dispersion curve file
   (this is file from disper.f)
   Example: earth.crv
earth.crv
   enter near offset:  xnear 
1
   enter group interval:  delx 
1
   enter number of receivers:  nrec
24
   enter minimum group velocity expected
100
  RECOMMENDED minimum tmax=    0.4800
   enter: maximum trace time, tmax
1.0
   enter: sample interval (seconds), fsamin
.001
   enter frequencies: fmin, fmax 
1., 100.
   enter maximum mode to include 
9
   enter ksw switch 0=c plot, 1=k plot
0
   enter type of plot format, mapmat
   0=octave (Matlab)  1=scilab
0
   enter Output option 0=Vertical  1=Radial 
0
   enter source depth
0
  enter (3) diagonal elements, moment tensor
0,0,1
  Padded Radix 2 tmax=    2.0480
  Number of points in signal= 2048
--------------------------------------------------
  .......Frequency interval=  0.48828122
  NOTE: Frequency Interval MUST MATCH DISPER OUTPUT
  WAVES will output signal length = 1.0/delf
  IF MISMATCHED: CHANGE sample rate in WAVES
                 or RERUN DISPER
--------------------------------------------------
  Number of frequencies=  204
  output in =====>waves.d
