.SH NAME
cssgrid_params \- This document briefly describes all the
internal parameters of Cssgrid.
.SH DESCRIPTION 
Each entry below includes the name of a parameter, its Fortran type
(use the obvious equivalents for C), 
its default value, and a short description of the parameter.  
.IP "\'SIG\'   -   Real   -    computed"
value of the tension factor for the splines 
.IP "\'TOL\'   -   Real   -   0.01"
Tolerance to use in calculating gradient differences to terminate the
iteration sequence when computing global gradients 
.IP "\'TTF\'   -   Real   -   0.01"
Tolerance to use in determining how accurately each tension factor should
be calculated to approximate its optimum value 
.IP "\'NLS\'   -   Integer   -   10"
Number of nodes to use in the least squares fit. 
.IP "\'NSG\'   -   Integer   -   10"
Maximum number of iterations to use in the algorithm for computing
automatic tension factors 
.IP "\'ISG\'   -   Integer   -   0"
Flag to revert to calculating automatic tension factors rather than
use a constant tension. Using a constant tension is effected by setting a
value for the control parameter sig. If isg is 0, then a tension
array is used, otherwise a constant tension is used. 
.IP "\'IGR\'   -   Integer   -   1"
Flags whether global or local gradients are used (1 implies
global, anything else implies local). 
.IP "\'MVL\'   -   Real   -   -8."
Fill value to use in returns for NCL functions. Used only
if mvl has been changed from its default.
