- 3
- Invalid dimension for longitudes in the output grid.
- 4
- First three nodes of input array are collinear.
- 5
- Extrapolation failed due to the uniform grid extending too far beyond the triangulation boundary.
- 6
- Internal algorithm error - please report this.
- 7
- Vertex of a triangle containing an interpolation point is outside its valid range.
- 8
- The angular distance between an interpolated point and the nearest point of the triangulation is at least 90 degrees.
- 9
- Not enough input points to calculate a gradient.
- 10
- Insufficient space for the triangulation (must be >= number of boundary nodes minus 2).
