RATIOS.f

RATIOS Manual Page

RATIOS is an auxillary program to plot surface abundances of user-selected nuclei, as a function of several possible variables, during the evolutionary sequence. It used data from the file hr.??. The graph may be seen onscreen via xwindows (device = '/xwin'), or sent to a file "postscript.ps" (device = '/cps') for color postscript.

Because of the problem with gfortran on OSX, it may be necessary to hack the file ratios.f (near the end at the "pause" statement), for desired behavior on your computer.

The control file is "ratios.in", listed below, should reside locally in the directory in which RATIOS is executed.

Meaning of new parameters:

  • The first integer is the number of nuclei used. This should be a multiple of 2 since the abundance ratios are for pairs of nuclei.
  • The following pairs of numbers of the charge number Z and the neutron number N of the nucleus.
  • The example shown (in commented form) has 2 (for two nuclei in one pair), followed by 6 6 (C12) and 6 7 (C13), so the ratio of C12/C13 by mass fraction will be ploted.

    • RATIOS will graph the model named in "cmod", with the usual parameters controling the graph.
