# Xsuwaveform1 - Demo shell script for program SUWAVEFORM
# Author: Nils Maercklin, 2006
#
# This demo shell script shows the generation of AKB or Ricker wavelets
# with different maximum or peak frequencies (X window plots).


# X window sizes and positions:
WIDTH=500
HEIGHT=700
WIDTHOFF1=50
WIDTHOFF2=600
HEIGHTOFF=50


# Create empty wavelet output files:
> akb_wavelet.su
> ricker_wavelet.su

# Generate AKB and zero-phase Ricker wavelets with different
# maximum or peak frequency fpeak, normalize by maximum amplitude,
# and store fpeak in header otrav for plotting:

for fpeak in 5 10 15 20 25 30
do
    # AKB wavelet:
    suwaveform type=akb fpeak=$fpeak ns=201 \
    | sushw key=otrav a=$fpeak \
    | sugain qbal=1 >> akb_wavelet.su
    
    # Ricker wavelet:
    suwaveform type=ricker1 fpeak=$fpeak ns=201 \
    | sushw key=otrav a=$fpeak \
    | sugain qbal=1 >> ricker_wavelet.su
