In our recent article (Pasam et al. Reference Pasam, Tudball Smith, Holmes, Burton and Thompson2023), there is an error in table 3 where the relative roughness for which the shear layer momentum thickness was estimated, has been mistakenly reported as k_s/D = 1.4 × 10⁻³ in the first two entries. This should instead be k_s/D = 1.9 × 10⁻³. The revised version is given in table 1 below.

Table 1. Momentum thickness ($\varTheta$/D) of the shear layer at different streamwise locations.

The authors would like to apologise for this oversight.
