Hello everyone,

I'm working with curve fitting, to smooth data but in the first place to
fill invalid positions in a curve.

I tend to use Gaussian equation, which works well so far. But it seems
that sometimes, I get undesired results, like the one from the attached
macro, where -995468 as curve point is calculated.

Is this an error/bug?

If this is correct, what would you suggest to avoid/remove such deflections?

Just out of curiosity. Is there an equation or function to interpolate
only missing positions of a curve, where each given point is kept?

Any help/hint is much appreciated.

Kind regards,
Rainer
