#======================================================================

# HISTORY:

#	Jul 26, 2015: - created from LWplot_prof_2beam

#	Jul 30, 2015: - moved main label outside plot area

#	Oct 12, 2015: - BUG: gaps were not plotted as such

#	Mar 16, 2016: - adapted to gmt5

#	Mar 17, 2016: - improved

#	May 18, 2016: - replaced rms tilt by mean tilt with traffic background

#				  - added plot_wprof_ymin tweakable

#	May 24, 2016: - BUG: ymin did not work for nsamp

#				  - fixed for partial-depth profiles

#				  - suppress plotting of nsamp == 0

# Tweakables:

#

# $plot_wprof_xmin = -0.27;

# $plot_wprof_ymin = 3600;

# $plot_wprof_ymax = 5000;

# $plot_wprof_xtics = "-0.25 -0.15 -0.05 0.05";
