The adjective is "luminous", not "luminescent", but yes! Thanks - it's good to get feedback on when I'm not clear. However, the word "luminosity" itself is only sort of metaphorical - it's a technical term I stole and repurposed from a philosophy article. The question is how far I can go with doing things like calling a post "You Are Likely To Be Eaten By A Grue" when decrying the hazards of poor luminosity.
My interpretation of your description had been that luminosity is like the bandwidth parameter in kernel density estimation.
We've had these for a year, I'm sure we all know what to do by now.
