comment Circular polarisation
Thank you. And, in this particular case, the conclusion of that is that for $E$ and $B$ to be a solutions of Maxwell's equations, that $k$ must have only $z$ component, because $E_0$ and $B_0$ are in the $x-y$ plane, and they're perpendicular. The fact that $\vec{B} = \vec{n}\times\vec{E}$ means that if $B$ makes circles, $E$ must make the too, right? So if they're asking me if those can be waves in the empty space, I should say that only if $k$ has only $z$ component, because otherwise they wouldn't be a solution to Maxwell's equation.?

Ok, that's good enough, I will accept this answer and follow your advice (it's totally not worth it). I will simplify things.

comment Dealing with experimental data
Ok, I see, what else would you need to know? The experiment is measuring values of pressure-volume to calculate isothermic curves. We then fit those curves to some equation of state, tipically Van der Waals, as we're dealing with phase transition, and we get the van der Waals coefficients, a, b, and the number of moles, n, I have to get these done for all three numbers. So what I have is 6 values (from six fits to 6 isothermic curves) for a,b,n. And now thinking about it, the error for each of them is the error of the fitting, not a systematic one. How would one approach this?

@dmckee Yes it's wrong, I'm fixing it, thanks, that was a typo.

Thanks for your answer. Systematic is probably a bad translation, I mean the error you make because of the instrument of measurement.
