6 cssgrid_params - This document briefly describes all the internal
7 parameters of Cssgrid.
8
10 Each entry below includes the name of a parameter, its Fortran type
11 (use the obvious equivalents for C), its default value, and a short
12 description of the parameter.
13
14 ´SIG´ - Real - computed
15 value of the tension factor for the splines
16
17 ´TOL´ - Real - 0.01
18 Tolerance to use in calculating gradient differences to
19 terminate the iteration sequence when computing global gradients
20
21 ´TTF´ - Real - 0.01
22 Tolerance to use in determining how accurately each tension
23 factor should be calculated to approximate its optimum value
24
25 ´NLS´ - Integer - 10
26 Number of nodes to use in the least squares fit.
27
28 ´NSG´ - Integer - 10
29 Maximum number of iterations to use in the algorithm for
30 computing automatic tension factors
31
32 ´ISG´ - Integer - 0
33 Flag to revert to calculating automatic tension factors rather
34 than use a constant tension. Using a constant tension is
35 effected by setting a value for the control parameter sig. If
36 isg is 0, then a tension array is used, otherwise a constant
37 tension is used.
38
39 ´IGR´ - Integer - 1
40 Flags whether global or local gradients are used (1 implies
41 global, anything else implies local).
42
43 ´MVL´ - Real - -8.
44 Fill value to use in returns for NCL functions. Used only if mvl
45 has been changed from its default.
