tpow=1		# gain power before examining autocorrelations
		# tpow=2 would often be better for field data

###PURPOSE###
# Same as in demo1, except here gapped decon comes before
# spiking decon.  Again, you are to assume that the decon
# parameters are estimated from the autocorrelation shown in
# frame two.  Also see demo1 for the comments on making the data.
	
# First make the synthetic data for the deconvolution demo.

# Plot the model
supswigp <modeldata title="Model Data: 64ms reverbs" \
	label1="Time (sec)" label2="Trace" >${demo}.1.eps

# Plot the autocorrelation with gain

supswigp title="Autocorrelation (with gain)" \
	label1="Time (sec)" label2="Trace" >${demo}.2.eps

# The autocorrelation shows that:
#       wavelet extends to about 30ms
#	first repetition ends at about 160ms
# this accords well with the actual 64ms reverberations and wavelet of 24ms
