NAME

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

DESCRIPTION

'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.
