NAME
fitgrid_params - This document briefly describes all the internal parameters of Fitgrid.

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   -    1.
    Value of the tension factor.

'SL1'   -   Real   -    0.
    The slope of the curve at the first point (see parameter SF1).

'SLN'   -   Real   -    0.
    The slope of the curve at the final point (see parameter SF1).

'SF1'   -   Integer   -    3
    Controls the use of parameters SL1 and SL2: 0=use both; 1=use SL1 only; 2=use SL2 only; 3=use neither.

'SF2'   -   Integer   -    3
    Controls the use of parameters SMT and EPS: 0=use neither; 1=use both; 2=use SMT only; 3=use EPS only.

'SMT'   -   Real   -   none
    Smoothing parameter for ftcurvs, ftcurvps, c_ftcurvs, and c_ftcurvps.

'EPS'   -   Real   -   none
    Smoothing parameter for ftcurvs, ftcurvps, c_ftcurvs, and c_ftcurvps.

'ZX1'   -   Real array   -   none
    X partials at left for ftsurf and c_ftsurf.

'ZXM'   -   Real array   -   none
    X partials at right for ftsurf and c_ftsurf.

'ZY1'   -   Real array   -   none
    Y partials at bottom for ftsurf and c_ftsurf.

'ZYN'   -   Real array   -   none
    Y partials at top for ftsurf and c_ftsurf.

'Z11'   -   Real   -   none
    X-Y partial at lower left for ftsurf and c_ftsurf.

'ZM1'   -   Real   -   none
    X-Y partial at lower right for ftsurf and c_ftsurf.

'Z1N'   -   Real   -   none
    X-Y partial at upper left for ftsurf and c_ftsurf.

'ZMN'   -   Real   -   none
    X-Y partial at upper right for ftsurf and c_ftsurf.

'DF1'   -   Integer   -   1
