Energy in the energy tidal frequency band tapers off, unable to find a minimum slope

[s1tsj]

Hi @kvos, thank you for all the help with regards to making sense of the script and getting the FES2014 model to run. I managed to get the diagrams for the energy tidal frequency band, but I'm confused by why I can't find the slope of the section of coast I used.

The energy in the energy tidal frequency band diagrams, for all transects drawn, appears to taper off without a defined minimum, continuously decreasing even when high values of max_slope were used for testing.

Attached is the notebook and the outputs, including the diagrams: notebook_1999-2020_slopecalculation.pdf Apologies for the extra comments and cells, I had to make these to successfully run the FES2014 model in a separate notebook and use the outputs from that to complete the rest of the processing in this notebook.

I'm looking for publications or documentation about how to interpret the power spectrum and tidal peak frequency bands to deduce what I've done incorrectly, but do you have any suggestions on what might've caused this?
