# Erratum: Collisional excitation of NH₃ by atomic and molecular hydrogen

by N. Bouhafs<sup>1</sup>, C. Rist,<sup>2</sup> F. Daniel,<sup>2</sup> F. Dumouchel,<sup>1</sup> F. Lique,<sup>1★</sup> L. Wiesenfeld<sup>2</sup> and A. Faure<sup>2★</sup>

**Key words:** errata, addenda – molecular data – molecular processes – radiative transfer – ISM: molecules.

There is a typographical error in equation (4) of Bouhafs et al. (2017). The correct analytical formula for the gas kinetic temperature is:

$$T_k = T_{1,2} \left\{ 1 - \frac{T_{1,2}}{T_0} \ln \left[ 1 + 1.608 \exp(-25.25/T_{1,2}) \right] \right\}^{-1}$$

The authors apologize for any inconvenience due to the possible use of the published equation and thank Rebeka Bögner for pointing out the error.
