Barycentric velocity distributions corresponding to various coordinate sets. Panel a: probability density function PDF(υ_bray) as computed with Eq. (13). Panels b-e: simulated barycentric velocity distributions for targets with a = 0 h, 6 h, 12 h, and 18 h, and δ = −22 deg, 0 deg, +30 deg, +60 deg, +90 deg, assuming one daily measurement over a time span of 1 yr and considering the target visibility. The second entry in the legend is the number of total observing nights. Panel ƒ: simulated barycentric velocity distribution of Wolf 294 (black line). The barycentric velocity distribution for the datasets of Wolf 294 (dashed red line) is overplotted.
