<p>What is W in the brightness (intensity) distribution, please?
Alpha is the position of the star; lambda, the wavelength; t, the time; P, the polarization.
Thank you</p>

If you can tell us where you found this, and perhaps provide some more context, it will be easier to help you.

Context is essential... there are some rough conventions of which symbols are used for which physical properties - but that is anything but a given. That is more true the less common a formula is. And this is not even a formula, but just a function call, so that no-one can even draw conclusions from the formula.

It was in a lecture about interferometry that in this all astrophysicists are interested. However, then it was talked just about the other variables as I described above.
