**Key words.** atomic data – atomic processes – molecular data – opacity – brown dwarfs – errata, addenda

Due to an error in the sampling of the autocorrelation function of the 4s X <fnref n="2" />Σ₁/₂-4p A Π₃/₂ transition, the opacity table for the D2 line at T = 800 K needs to be corrected. The theoretical K-He profile at T = 800 K shown in Fig. 6 is correct. Consequently, revised opacity tables of K-He will be archived at the CDS.

## Data availability

K-He opacity tables for the D1 and D2 components of the resonance line are available at the CDS via anonymous ftp to cdsarc.cds.unistra.fr (130.79.128.5) or via https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/683/A188.

*Acknowledgements.* N.F. Allard is grateful to Nikola Vitas for identifying a problem in the public data for the D2 line of K-He at *T* = 800 K published in the original paper.
