Query: Spectroscopic line parameters of NO, NO$_2$, and N$_{2}$O for the HITEMP
  database   This work describes the update of NO along with the incorporation of NO$_{2}$
and N$_{2}$O to the HITEMP database. Where appropriate, the HITRAN line lists
for the same molecules have also been updated. This work brings the current
number of molecules provided by HITEMP to seven. The initial line lists
originating from \textit{ab initio} and semi-empirical methods for each
molecule have been carefully validated against available observations and,
where necessary, adjustments have been made to match observations. We
anticipate this work will be applied to a variety of high-temperature
environments including astronomical applications, combustion monitoring, and
non-local thermodynamic equilibrium conditions.
