NAME

6       cssgrid_params - This document briefly describes all the internal
7       parameters of Cssgrid.

DESCRIPTION

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.
