Now, this project when they did it, they they came up with a formula for that, I am not writing the formula, but typically that formula will show that this this spectrum for the same energy is much peak year then compare to say for example, my ITTC Spectrum. This may be the ITTC Spectrum this will be JONSWAP, why I mentioned is, because JONSWAP Spectrum turned out when you collected data there it it turned out that, there is a tendency for wave of one particular length to be much more number. So, it is what is called peaky spectrum, very much peaked now.
