1 TABLE_DENSITY  Density of points from 2 columns of a table

           Compute a 2-D image with the density of points
       from 2 columns of an input table. Also create a table
       containing only the "isolated" points, those with a
       density below some threshold.

       The task is used by the  "plot-triangle.greg" procedure
       to display correlation analysis of N parameters, from a
       M x N table containing M valid samples of the N parameters.
2 NAME_IN$
        TASK\CHARACTER "Input Table"  NAME_IN$

      Name of input table. The default extension is .tab
2 COLS$
        TASK\INTEGER "X and Y columns" COLS$(2]

      X and Y Column numbers

2 NAME_OUT$
        TASK\CHARACTER "Output Image"  NAME_OUT$

      Name of the output density image. The default extension is .gdf

2 DIMS$
        TASK\INTEGER "Image size" DIMS$[2]

      Size of the output density image. The default value is 16,
      which is suited for sample sizes below 5000. 32 would fit
      up to 50000, 64 would start being usable above.

2 TABLE_OUT$
        TASK\CHARACTER "Output Table"  TABLE_OUT$

      Table containing only the points below the threshold density
      given in PERCENT$.

2 PERCENT$
        TASK\REAL "Threshold (in %)" PERCENT$

      Threshold to retain the individual points. The default value,
      30 % is adequate for the default contouring at 20, 40, 60, 80 percent.
