It's pretty clear that this is a step function convolved with a gaussian.
This is my gaussian

Using the deconvolution fuction i got not sense results, i.e. i obtain a wave-like function.

Any idea about this strange behaviour ?

Best regards,
Andrea

Did two columns share the same X, i.e. the same start time and sampling interval?

I test convolving a step signal with a gaussian function in Origin. Then deconvolve the convoluted signal with the gaussian function in Origin. The deconvolved result agrees with the step signal.
