hi everybody ,

I know this could be a bit weird to ask and sorry if this question seems stupid (I would have asked this in private message to someone but I can't send private messages) but:
I know T = 1/f so f=1/T
btw is the Minimum frequency = 1/ maximum period ?
is the Peak frequency = 1/ minimum Period ?

sorry again

Josias

I know peak period = 1/ peak frequency
but i got 50 % of waves around 9s
24% under 7s
24% over 11s

min T = 5s
max T = 18s

I don't know which value to use to set the tom steering file

Hi Josias,

Let's say we have a wave spectrum (attached is an example), the y-axis is wave energy (simplified as a^2/2, a is wave amplitude) and the x-axis is frequency. The corresponding frequency of the spectrum peak (max. wave height/amplitude) is the so-called peak frequency.

I'm not an expert of TOMAWAC, but I hope this will give you a hint to set your tom steering file.
