Question regarding the model output

Hello!

I am trying to use the FES for tidal prediction in Brazil. I was able to successfully run the model and generate some outputs but I am having trouble regarding understanding the output provided by the model. For instance, it outputs "short_tide", "lp_tide", "pure_tide", "geo_tide" and "rad_tide". I was not able to find what are they from the documentation. What are they exactly? Which column better represent the real tide?

Thank you!
