SIGMA.TXT

Description

This text file is essentially a copy of the most recently made ICQ shape file SHAPE.TXT that includes an additional column of sigma values.

SIGMA.TXT is made by densify and is located in the SHAPEFILES/ directory.

Here is a sample SIGMA.TXT file:

     0.01239     0.19615     0.13521         0.28469E-01
     0.01300     0.19594     0.13549         0.28856E-01

The output values are:

Line 1 - Q (resolution). This gives the number of nodes for i and j. Multiple Q by 6 coordinate vector spaces to fill out the entire region.

Lines 2 and following - The location of a vertex in i, j, k space (Cartesian coordinates).
