NAME

       c_nngetaspectd - retrieve a double precision aspect at a specified coordinate.

FUNCTION PROTOTYPE

       void c_nngetaspectd(int, int, double *, int *);

SYNOPSIS

       c_nngetaspectd (row, column, aspect, ier);

DESCRIPTION

       row         A subscript indexing the first dimensioned variable in the 2D grid array
                   returned from the most recent call to c_natgridd.

       column      A subscript indexing the second dimensioned variable in the 2D grid array
                   returned from the most recent call to c_natgridd.

       aspect      *aspect is the aspect at the grid point z[i,j], where z is the output grid in
                   the most recent call to c_natgridd.

       ier         An error value. If *ier is 0, then no errors were detected. If *ier is non-
                   zero, then refer to the man page for natgrid_errors for details.

USAGE

       This routine allows you to retrieve the current value of Natgrid parameters.  For a
