temperatures.

Line lists for hot H$_2$$^{17}$O and H$_2$$^{18}$O will also be released very shortly [@jtiso]. Again these will take advantage of the available set of experimental energy levels [@jt454; @jt482] obtained using the MARVEL procedure [@jt412; @12FuCsi.method]. These line lists will be as complete as BT2 and consider levels with $J
\leq 50$ and energies up to 30 000 [cm$^{-1}$]{}.

NH$_3$
------

Ammonia is a ten electron system like water, so in terms of electronic calculations one might expect similar improvements here too. $^{14}$NH$_3$ has also been the subject of a systematic study of experimental energy levels [@jt608] and improvements in its [*ab initio*]{} treatment [@11HuScLe.NH3; @jt634]. New experimental data characterizing higher-lying energy levels is also available [@jt616; @jt633]. Again the Ames group have performed high accuracy studies on this system [@11HuScLe.NH3; @11HuScLe2.NH3; @12SuBrHu.NH3], although there is no corresponding line list. Work is therefore in progress to compute a new ammonia line list which will replace the existing BYTe line list [@jt500]; in particular this work the option of using the improved nuclear motion capability of the program [TROVE]{} working in curvilinear coordinates [@15YaYuxx.method]. Recent, excellent [*ab initio*]{} calculations [@jt634] which reproduce very highly excited energy levels of ammonia up
