Planetary nebula luminosity function — (PNLF) is a secondary distance indicator used in astronomy. It makes use of the [O III| [O III] λ5007 forbidden line found in all planetary nebula which are members of the old stellar populations (Population… … Wikipedia
Jansky — In radio astronomy, the flux unit or jansky (symbol Jy) is a non SI unit of electromagnetic flux density equivalent to 10−26 watts per square metre per hertz. The flux density or monochromatic flux , S, of a source is the integral of the spectral … Wikipedia
