Undefined variable used at the end of tutorial 6 of the deconvolution

[BjoernLudwigPTB]

We noticed there is probably something missing at the very end of the deconvolution tutorials. Please check the output at the very end of tutorial 6 on mybinder .

In calculate_freq_points there is an undefined parameter Nf used.

We already prepared a branch fix_deconvolution_tutorial, in which we can work on this. The current main branch does not produce this error anymore, to avoid a failing pipeline. But of course we simply outcommented the corresponding section and should definitely fix that soon.
