Figures number 2 - 7 and 12 can be plotted using the IDL code "fig_pop16.pro" with argument fig = figure number. Note that "fig_pop16.pro" uses "colobar.pro".
For example, in order to generate figure #2, at IDL prompt type: 
  fig_pop16, f=2

Figures number 1, 8-11, and 13 can be plotted using "Gnuplot" scripts with corresponding names.
For example, for figure 1, type: 
 load 'fig1.gnu'
in the Gnuplot prompt.


List of data files corresponding to different figures is given below.
All data is in ASCII format.

Gnuplot figures (1,8-11,13):
