| emissivity |
the ratio of radiant energy from a material to that from a blackbody at the same kinetic temperature. Materials may have wavelength-dependent emissivities between 0 and 1.0. (approximately the inverse of reflectance)

| emissivity |
The intrinsic strength of an atomic transition that produces a spectral line. The term encapsulates all the atomic data information needed to calculate the flux. It is often generalized to also refer to continuum processes. Units are usually [10 -23 ergs cm 3 s -1 ]. Sometimes also presented as [ph cm 3 s -1 ], and especially for continuum emissivities, [(erg|ph) cm 3 s -1 ?-1 ]
