While it is true having oil production is an indicator of a country's production potential, I wonder how things would look if this range of light was removed.

Otherwise my inference from the article is that there's no overlap. So how could anyone know that luminosity is measuring the same thing as all those economic indicators, or at least that it's calibrated right?
