- Standard candles are objects whose intrinsic brightness or luminosity we know really well.
- intrinsic luminosity
- luminosity of stars
- integrated luminosity
So what you would find would be a very rapid fall off of luminosity with distance.
- So what you would find would be a very rapid fall off of luminosity with distance.
- Because yellow light would trigger our red cone about right here at its peak, and our green cone somewhere in the middle of its peak luminosity.
Examples
-
Astronomers also used RR Lyrae variables as standard candles because they all have the same luminosity.

Their energies could be a whopping one quintillion times the luminosity of the Sun.
Academic text (1994) -

Etymology
Luminosity comes from the Latin lumen meaning 'light' and the ending -osity meaning 'a quality', and it shares the same root as luminous and luminary. So when scientists or artists talk about a star's or a painting's luminosity, they mean its brightness — how much light it gives or reflects.
