       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

              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
              Flag indicating if ZX1 is user supplied: 0=yes; 1=no.

       ´DF2´   -   Integer   -   1
              Flag indicating if ZXM is user supplied: 0=yes; 1=no.

       ´DF3´   -   Integer   -   1
              Flag indicating if ZY1 is user supplied: 0=yes; 1=no.

       ´DF4´   -   Integer   -   1

       ´DF5´   -   Integer   -   1
              Flag indicating if Z11 is user supplied: 0=yes; 1=no.

       ´DF6´   -   Integer   -   1
              Flag indicating if ZM1 is user supplied: 0=yes; 1=no.

       ´DF7´   -   Integer   -   1
              Flag indicating if Z1M is user supplied: 0=yes; 1=no.

       ´DF8´   -   Integer   -   1
              Flag indicating if ZMN is user supplied: 0=yes; 1=no.
