A far wing corrective factor chi for CH4 lines broadened by H-2 is proposed
. It has been deduced from laboratory spectra measured in the nu (3) band r
egion at various temperatures between 100 and 300 K. Its quality is demonst
rated by comparisons of synthetic spectra with laboratory experiments as we
ll as with the spectrum of the jovian atmosphere observed by ISO. (C) 2001
