bolometric absolute magnitude (Mbol)
subject			fact

bolometric absolute magnitude	has symbol Mbol
	has definition A measure of the total amount of energy radiated by a star at all wavelengths. Mbol of Sun = 4.72 mag. The fraction of total energy emitted by a very blue or very red star that lies in the visible range may differ from the total energy by 4 or 5 mag - i.e., only a few percent of the energy lies in the visible.
	is a kind of absolute magnitude
radiation measurement	has unit radiation unit
number	has value
