# Data and gnuplot tips for problem 7.8 (Tinoco et al.)
# tip: to plot time v. c, use: 
#	gnuplot> plot 'prob_7_8.dat' using 1:2
# 	to fit: 
#	gnuplot> fit a*x+b 'prob_7_8.dat' using 1:2 via a,b
#	then, 
#	gnuplot> replot a*x+b
# Note: in Gnuplot the expression log(x) is actually ln(x), or 2.303*log(x)
# tip: to plot t v. ln(c), use: 
#	gnuplot> plot 'prob_7_8.dat' using 1:(log($2))
# 	to fit: 
#	gnuplot> fit a*x+b 'prob_7_8.dat' using 1:(log($2)) via a,b
#	then, 
#	gnuplot> replot a*x+b
# tip: to plot t v. 1/c, use: 
#	gnuplot> plot 'prob_7_8.dat' using 1:(1/$2)
# 	to fit: 
#	gnuplot> fit a*x+b 'prob_7_8.dat' using 1:(1/$2) via a,b
#	then, 
#	gnuplot> replot a*x+b
# Here's the data
