DESCRIPTION

10       Each entry below includes the name of a parameter, its Fortran type
11       (use the obvious equivalents for C), its default value, and a short
12       description of the parameter.
13
14       ´ADF´   -   Integer   -    0
15              Flags if the data file of algorithmic information for display
16              with nnalg is produced - see parameter alg (0=no; 1=yes).
17
18       ´ALG´   -   Character   -   ´nnalg.dat´
19              File name for input to the algorithmic display tool nnalg (see
20              parameter adf).
21
22       ´ASC´   -   Integer   -   1
23              Flags if automatic scaling is allowed (0 = no; 1 = yes).
24
25       ´bI´   -   Real   -   1.5
26              Tautness factor that increases the effect of the gradient
27              estimates as bI increases.
28
29       ´bJ´   -   Real   -   7.0
30              Tautness factor that decreases the breadth of the region
31              affected by the gradient estimates as bJ increases.
32
33       ´EXT´   -   Integer   -   1
34              Flags whether extrapolation is allowed outside the convex hull
35              (0=no; 1=yes).
36
37       ´HOR´   -   Real   -   0.1*(extent of X output grid)
38              Specifies the amount of horizontal overlap to be included
39              outside of the current region when doing subblocking.
40
41       ´IGR´   -   Integer   -   0
42              Flag indicating if gradient estimates are to be computed (1=yes;
43              0=no).
44
45       ´MAGX´   -   Real   -   1.0
46              Scale factor for X coordinate input values.
47
48       ´MAGY´   -   Real   -   1.0
49              Scale factor for Y coordinate input values.
50
51       ´MAGZ´   -   Real   -   1.0
52              Scale factor for Z coordinate input values.
53
54       ´MDM´   -   Integer   -   10
55              Maximum number of informational messages about duplicate point
56              culls.
57
58       ´NON´   -   Integer   -   0
59              Flags whether interpolated values are allowed to be negative
60              (0=yes; 1=no).
61
62       ´NUL´   -   Real   -   0.0
63              The value to be used on output for points outside of the convex
64              hull when extrapolation is not allowed.
65
66       ´RAD´   -   Integer   -   0
67              Flags if slopes and aspects are returned in radians or degrees
68              (1=radians;0=degrees).
69
70       ´SDI´   -   Integer   -   0
71              Flags if slopes and aspects are computed (0=no; 1=yes).
72
73       ´UPD´   -   Integer   -   1
74              Flags if the output array goes from south to north or north to
75              south (0=north to south; 1=south to north).
76
77       ´VER´   -   Real   -   0.1*(extent of Y output grid)
78              Specifies the amount of vertical overlap to be included outside
79              of the current region when doing subblocking.
80
81       ´XAS´   -   Real   -   1.0
82              Contains the scale value for automatic scaling of X input values
83              in the most recent interpolation call.  For retrieval only.
84
85       ´YAS´   -   Real   -   1.0
86              Contains the scale value for automatic scaling of Y input values
87              in the most recent interpolation call.  For retrieval only.
88
89       ´ZAS´   -   Real   -   1.0
90              Contains the scale value for automatic scaling of Z input values
91              in the most recent interpolation call.  For retrieval only.
