NAME

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

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.

       ´SIG´   -   Real   -    computed
              value of the tension factor for the splines

       ´TOL´   -   Real   -   0.01
              Tolerance to use in calculating gradient differences to terminate the iteration
              sequence when computing global gradients

       ´TTF´   -   Real   -   0.01
              Tolerance to use in determining how accurately each tension factor should be
              calculated to approximate its optimum value

       ´NLS´   -   Integer   -   10
              Number of nodes to use in the least squares fit.

       ´NSG´   -   Integer   -   10
              Maximum number of iterations to use in the algorithm for computing automatic
              tension factors

       ´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.

       ´IGR´   -   Integer   -   1
              Flags whether global or local gradients are used (1 implies global, anything else
              implies local).

       ´MVL´   -   Real   -   -8.
              Fill value to use in returns for NCL functions. Used only if mvl has been changed
              from its default.
