(total luminosity of an object at all wavelengths)
Bolometric luminosity (LBol)
is an astronomical body's total power output across
all EMR wavelengths.
A bolometer is a device that measures incoming EMR
at all wavelengths (or at least over a significant wavelength range),
and luminosity is the power output of an astronomical body.
The term luminosity, unqualified and devoid of a context
that implies otherwise is generally used to mean bolometric luminosity.
Bolometric magnitude is a logarithmic measure of
the same value.
