natgrid_params - This document briefly describes all the internal
parameters of Natgrid.
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.
- ´ADF´ - Integer - 0
- Flags if the data file of algorithmic information for display with nnalg
is produced - see parameter alg (0=no; 1=yes).
- ´ALG´ - Character - ´nnalg.dat´
- File name for input to the algorithmic display tool nnalg (see parameter
adf).
- ´ASC´ - Integer - 1
- Flags if automatic scaling is allowed (0 = no; 1 = yes).
- ´bI´ - Real - 1.5
- Tautness factor that increases the effect of the gradient estimates as bI
increases.
- ´bJ´ - Real - 7.0
- Tautness factor that decreases the breadth of the region affected by the
gradient estimates as bJ increases.
- ´EXT´ - Integer - 1
- Flags whether extrapolation is allowed outside the convex hull (0=no;
1=yes).
- ´HOR´ - Real - 0.1*(extent of X output grid)
- Specifies the amount of horizontal overlap to be included outside of the
current region when doing subblocking.
- ´IGR´ - Integer - 0
- Flag indicating if gradient estimates are to be computed (1=yes;
0=no).
- ´MAGX´ - Real - 1.0
- Scale factor for X coordinate input values.
- ´MAGY´ - Real - 1.0
- Scale factor for Y coordinate input values.
- ´MAGZ´ - Real - 1.0
- Scale factor for Z coordinate input values.
- ´MDM´ - Integer - 10
- Maximum number of informational messages about duplicate point culls.
- ´NON´ - Integer - 0
- Flags whether interpolated values are allowed to be negative (0=yes;
1=no).
- ´NUL´ - Real - 0.0
- The value to be used on output for points outside of the convex hull when
extrapolation is not allowed.
- ´RAD´ - Integer - 0
- Flags if slopes and aspects are returned in radians or degrees
(1=radians;0=degrees).
- ´SDI´ - Integer - 0
- Flags if slopes and aspects are computed (0=no; 1=yes).
- ´UPD´ - Integer - 1
- Flags if the output array goes from south to north or north to south
(0=north to south; 1=south to north).
- ´VER´ - Real - 0.1*(extent of Y output grid)
- Specifies the amount of vertical overlap to be included outside of the
current region when doing subblocking.
- ´XAS´ - Real - 1.0
- Contains the scale value for automatic scaling of X input values in the
most recent interpolation call. For retrieval only.
- ´YAS´ - Real - 1.0
- Contains the scale value for automatic scaling of Y input values in the
most recent interpolation call. For retrieval only.
- ´ZAS´ - Real - 1.0
- Contains the scale value for automatic scaling of Z input values in the
most recent interpolation call. For retrieval only.
