Following are CWP id flags:
9 = Autocorrelation
10 = Fourier transformed - no packing xr[0],xi[0], ..., xr[N-1],xi[N-1]
11 = Fourier transformed - unpacked Nyquist xr[0],xi[0],...,xr[N/2],xi[N/2]
12 = Fourier transformed - packed Nyquist even N: xr[0],xr[N/2],xr[1],xi[1], ..., xr[N/2 -1],xi[N/2 -1] (note the exceptional second entry)
odd N: xr[0],xr[(N-1)/2],xr[1],xi[1], ..., xr[(N-1)/2 -1],xi[(N-1)/2 -1],xi[(N-1)/2] (note the exceptional second & last entries)
13 = Complex signal in the time domain xr[0],xi[0], ..., xr[N-1],xi[N-1]
14 = Fourier transformed - amplitude/phase a[0],p[0], ..., a[N-1],p[N-1]
15 = Complex time signal - amplitude/phase a[0],p[0], ..., a[N-1],p[N-1]
16 = Real part of complex trace from 0 to Nyquist 17 = Imag part of complex trace from 0 to Nyquist 18 = Amplitude of complex trace from 0 to Nyquist 19 = Phase of complex trace from 0 to Nyquist 21 = Wavenumber time domain (k-t) 22 = Wavenumber frequency (k-omega) 23 = Envelope of the complex time trace 24 = Phase of the complex time trace 25 = Frequency of the complex time trace 30 = Depth-Range (z-x) traces 43 = Seismic Data, Vertical Component 44 = Seismic Data, Horizontal Component 1 45 = Seismic Data, Horizontal Component 2 46 = Seismic Data, Radial Component 47 = Seismic Data, Transverse Component 101 = Seismic data packed to bytes (by supack1) 102 = Seismic data packed to 2 bytes (by supack2)
