# Demos shell for sugoupillaudpo
# Albena Mateeva, Feb, 2002

#----------------------------------------------------------------------------
# Example reflection coefficient series: rdemo.asc
#
# rdemo.asc has 250 samples:
# The first one, r[1]=-1.0, represents the earth surface (free surface);
# r[2]:r[250] represent subsurface interfaces equally spaced in time (dt=2ms).
#
#
# Creating input file for sugoupillaudpo:
#
a2b n1=1 < rdemo.asc | suaddhead ns=250 | sushw key=dt a=2000 > rdemo.su
#
#--------------------- show example reflectivity:
