Are the polarization data consistent with constant flux models of Titan's atmosphere?

The consequences of the assumption that the mass flux through Titan's atmosphere is independent of height, when it is applied to the model of M. G. Tomasko and P. H. Smith (1982, Icarus51, 65–95) for the Voyager IPP polarization measurements, is explored. It is found that one of the basic assumptions of the constant flux model must be altered in order to make it consistent with both the polarization data and the observed equivalent widths of the methane bands.
