NAME

Ftplot - plots the input time-series and output FT


SYNOPSIS

Ftplot par= < in.H | Xtpen


DESCRIPTION

Outputs vplot commands to plot an input time-series and its Fourier amplitude or phase spectrum.


INPUT PARAMETERS

f2 - int
      [0]  number of traces to skip before reading from in
fmin -float
      [0.] minimum frequencies to plot
fmax- int
      [1/2dt] maximum frequencies to plot
plot- char*
      [amp ] -to plot AMPLITUDE (NORMALIZED) spectrum.
      db     - to plot AMPLITUDE (DB) spectrum.
      pha    - to plot PHASE (DEGREES) spectrum.
      upha   - to plot unwrapped PHASE (DEGREES) spectrum.
lfft-int
      length of fft used to compute spectrum
      input padded with zeros if lfft > nt
wate-char*
      [no] -weighting to apply to input before Fourier 
      transforming for rectangular weighting
      ham -for Hamming weighting
n1,n2 -int
