Notes. The error in the center was calculated considering the contribution of the error in the Gaussian fit and in the stellar radial velocity. The [O I] lines at λ6300 and λ6363 of V853 Oph were fitted using the sum of two Gaussians to account for the low and high-velocity components (LVC and HVC), while flux and equivalent width were calculated for the sum of the two components.
