model [@12AlHoFr] and provides the hot water line list for HITEMP [@jt480]. However, although it is more complete, for many levels it is less accurate than the Ames line list of Partridge and Schwenke [@97PaScxx.H2O]. Since the construction of BT2 there has been significant progress in deriving experimental energy levels for H$_2$$^{16}$O [@jt539; @jt562], improvements in the [*ab initio*]{} dipole moment surface [@jt509] which have been used to construct high accuracy room temperature line lists [@jt522] and further improvements in representing the potential energy surface of the molecule [@jt519]. A new H$_2$$^{16}$O line list, named POKAZATEL, [@jtpoz] which builds on these advances will be released soon. The completeness of this line list is illustrated by the following figures: The highest rotational quantum number used in the calculations of the wavefunctions was $J=72$ — close to the highest $J$ for wich the bound states still do exist. The highest upper energy levels limit is equal to 40 000 [cm$^{-1}$]{}, which is also close to the dissociation limit of water [@jt549].

While the BT2 and Ames line lists are seriously incomplete for temperatures above 3000 K, POKAZATEL considers every ro-vibrational transition in the molecule and therefore is appropriate for studies at higher
