7       coordinate.

SYNOPSIS

10       CALL NNGETASPECTD (I,J,ASPECT,IER)
11

DESCRIPTION

13       I           (Integer, Input) - A subscript indexing  the  first  dimen‐
14                   sioned  variable in the output grid of the most recent call
15                   to NATGRIDD.
16
17       J           (Integer, Input) - A subscript indexing the  second  dimen‐
18                   sioned  variable in the output grid of the most recent call
19                   to NATGRIDD.
20
21       ASPECT      (Double precision, Output) - The slope at  the  grid  point
22                   Z(I,J),  where Z is the output grid in the most recent call
23                   to NATGRIDD.
24
25       IER         (Integer, Output) -  An  error  return  value.  If  IER  is
26                   returned as 0, then no errors were detected. If IER is non-
27                   zero, then refer to the man  page  for  natgrid_errors  for
28                   details.
