Although the YT10to10 line list [@jt564] represents a major step forward in the modelling of hot methane spectra [@jt572], it does not represent a complete solution to the problem. Rey [[*et al*]{}]{} [@14ReNiTy.CH4] have also produced a line list, using similar procedures to those adopted by ExoMol, valid to higher temperatures (2000 K) but covering a more limited spectral range. The temperature coverage can be checked using available, high-temperature partition functions [@08WeChBo.CH4; @15NuKrRe.CH4].

Yurchenko [[*et al*]{}]{} [@jtCH4] have extended the YT10to10 line list to higher temperatures (2000 K) and improved the predicted frequencies by replacing computed energy levels with empirical ones provided by Boudon [@14Boudon.CH4]. The resulting line list has 35 billion transitions and Yurchenko [[*et al*]{}]{} propose that most of the lines in the line list can be represented by background cross sections. These temperature-dependent, but pressure-independent cross sections, generated using the vast majority of the lines, can then be used to supplement a reduced line list of 203 million lines selected to be the strongest in each spectral region. If this methodology proves successful, it will be adopted by
