The correction for air mass variations within the samples has been made with a radiative transfer model of the limb brightening. This model indicates that the C 2 H 2 Q-branch emission (line minus nearby continuum) doubles when the air mass (or the column abundance) is increased by a factor of 3 whereas the C 2 H 6 line emissions are multiplied by a factor of 2.6. In the case of CO 2 and HCN the emission is proportional to the air mass. The raw intensities of the emission features are first corrected for this effect and then divided by the Planck function at 5 mbar (C 2 H 2 and C 2 H 6 ) or 1.0 mbar (CO 2 and HCN) (normalized at 45\u00b0S) taken from the zonal mean temperature maps derived from CIRS data ( 20 ). This approximately corrects the dependence of the emission upon temperature given that the contribution functions peak around 5 mbar for the two hydrocarbons and around 0.2 mbar for CO 2 and HCN."},{"key":"e_1_3_1_15_2","doi-asserted-by":"publisher","DOI":"10.1006\/icar.2002.6929"},{"key":"e_1_3_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.icarus.2004.02.006"},{"key":"e_1_3_1_17_2","unstructured":"J.
