The 4π confusion Therefore, we propose that photometric measurements of the airglow and aurora be reported in terms of 4πB rather than the surface brightness B itself. Further, we suggest that 4πB be given the unit “rayleigh” (symbol R), where B is in units of 10 6 quanta cm −2 s −1 sr −1 . Hence 1 R = 10 6 quanta cm −2 (column) −1 s −1 . Hunten et al. [1956] So does both Hunten et al. [1956] and Chamberlain [1995] claim that 4π × 10 6 = 10 6 ??? UNIS 2011-11-15 – p. 29
Can we agree on this? The apparent radiance (Lγ) can be obtained from the column emission rate I (in Rayleighs) according to Baker and Romick [1976]: (5) Lγ = 1010 I 4π photons s m 2 sr UNIS 2011-11-15 – p. 30
